what is the stretching frequency (in cm-1) of the following carbonyl? group of answer choices 1655 1685

Answers

The stretching frequency (in cm⁻¹) of the given carbonyl compound is 1685 cm⁻¹

The carbonyl group, C=O, has a large dipole moment and it creates an intense stretching vibration whose peak generally appears between 1600 to 1800 cm⁻¹.

The spectrum shows a stretching absorption consistent with a ketone functional group, i. e. carbonyl group C=O stretching at ~1685 cm⁻¹.

Definition: Stretching frequencies are higher than corresponding bending frequencies. It is easier to bend a bond than to stretch or compress it.

The distinctive carbonyl band is particularly useful for diagnostic purposes because it has a characteristic high intensity and few other functional groups absorb in this region.

Different carbonyl compounds absorb in narrow ranges within the general carbonyl region.

Why do some glucose molecules move out of
the blood and others move into it?

Answers

Due to process of facilitated diffusion some glucose molecules move out of the blood and others move into it.

Facilitated diffusion :

The diffusion of solutes across the plasma membrane is facilitated by transport proteins. Passive transport is facilitated diffusion. Even though transport proteins are involved in facilitated diffusion, it is still passive transport because the solute is moving across the concentration gradient.

Why is it called facilitated diffusion?

Passive transportation is facilitated transport. Unlike simple diffusion, which occurs when materials pass through a membrane without the assistance of proteins, facilitated transport, also known as facilitated diffusion, occurs when materials diffuse across the plasma membrane with the assistance of membrane proteins.

Importance of Facilitated Diffusion

To move molecules from one side of the membrane to the other without using energy, facilitated diffusion is required. Large and charged molecules, in particular, benefit from facilitated diffusion. These molecules cannot move freely across the plasma membrane due to simple diffusion.

Which bases can be used to deprotonate a terminal alkyne? choose all that apply.

Answers

NaNH₂ can be used to deprotonate a terminal alkyne.

An analogous term (pKa) can be used to describe the acidity of terminal alkynes because they are mildly (i.e. weak) acidic. In this case, too, the lower the pKa value, the stronger the acid.

Alkynes have pKa values of around 25, therefore sodium amide, or NaNH₂, is an excellent (strong, that is) base that can deprotonate them. Indeed, sodium amide does deprotonate terminal alkynes (it can be used for elimination reactions, too).

This is possible because the NH₂⁻ anion is the conjugate base of Ammonia (NH₃) and, as a general acid-base principle, the weaker the acid, the stronger its conjugate base (Conjugate acid). Since ammonia has a pKa of about 38, NH₂⁻ is indeed a very strong base.

Sodium amide can deprotonate terminal alkynes (and alcohols, too) and it is often used when an Acetylide ion (RC₂⁻) is needed. These ions are then extremely helpful intermediates in the synthesis of organic compounds because they can react in a wide range of reactions as nucleophiles.

sugar cane is gathered and then treated with water to create raw juice, which has a low pH and dissolved contaminants. To increase the pH and react with the contaminants to create soluble calcium organic compounds that can be removed, hydrated lime is added to the juice. Lime excess is eliminated through carbonation or phosphoric acid addition. Depending on the needed level of final product purity, this process could be done numerous times.Two independent processes are involved in the production of sugar: (a) turning sugar cane or sugar beets into raw sugar, and (b) turning the raw sugar into refined sugar.

What mass of copper atoms have the same number of atoms as there are in a 4.21 gram sample of silicon?

Answers

The mass of copper atoms have the same number of atoms as there are in 4.21 g sample of silicon is 9.55 g

Avogadro's hypothesis

1 mole of silicon = 6.02×10²³ atoms

But

1 mole of silicon = 28 g

Thus, we can say that:

28 g of silicon = 6.02×10²³ atoms

How to determine the atoms in 4.21 g of silicon

28 g of silicon = 6.02×10²³ atoms

Therefore,

4.21 g of silicon = (4.21 × 6.02×10²³) / 28

4.21 g of silicon = 9.05×10²² atoms

Thus, 9.05×10²² atoms is present in 4.21 g of silicon

How to determine the mass of copper that contains 9.05×10²² atoms

From Avogadro's hypothesis ,

6.02×10²³ atoms = 1 mole of copper

But

1 mole of copper = 63.55 g

Thus, we can say that:

6.02×10²³ atoms = 63.55 g of copper

Therefore,

9.05×10²² atoms = (9.05×10²² × 63.55) / 6.02×10²³

9.05×10²² atoms = 9.55 g of copper

among the elements of the main group, the general trend in the first ionization energy moving across a period is not followed between group 2 and group 13. which best explains these exceptions?

Due to the full s orbital's protection of the electron entering the p orbital, the ionization energy drops.

The full s orbital shields the electron as it enters the p orbital, lowering the ionization energy.

This process of "shielding" reduce s the net force acting on the outer shell electrons by a large amount when each new electron experiences both nucleon attraction and S orbital repulsion forces. Ionization energy consequently drops during these groupings.

The energy needed to free the outermost, or least bound, electron from an element's neutral atom is known as the first ionisation energy.

Answers

The flame test is used to visually determine identity of an unknown metal or metalloid ion based on characteristic color the salt turns the flame of a Bunsen burner. The heat of flame excites the electrons of the metals ions, causing them to emit visible light. Every element has a signature emission spectrum that can be used to differentiate the between one element and another.

How to Do Flame Test?

First, you need clean wire loop. Platinum or nickel-chromium loops are the most common. They may be cleaned by dipping in the hydrochloric or nitric acid, followed by rinsing with distilled or deionized water. Test cleanliness of the loop by inserting it into a gas flame. If a burst of color is produced, loop is not sufficiently clean. The loop must be cleaned between the tests.

The clean loop is dipped in either a powder or a solution of an ionic (metal) salt. The loop with sample is placed in a clear or blue part of the flame and the resulting color is observed.

Key Takeaways: Perform Flame Test:

The flame test is qualitative test in analytical chemistry used to help identify the composition of a sample.The premise is that heat gives energy to the elements and ions, causing them to emit light at a characteristic color or emission spectrum.The flame test is a quick way to narrow down identity of a sample, but must be combined with other tests to confirm composition.

how many protons, neutrons and electrons are there in a neutral atom of the isotope of chlorine named chlorine-35?

Answers

Taking into account the definition of mass number, atomic number and charge of an atom, the number of protons and electrons of the isotope of chlorine named chlorine-35 is 17, while the number of neutrons is 18.

Subatomic particles

All atoms are made up of subatomic particles: protons and neutrons, which are part of their nucleus, and electrons, which revolve around them.

Atomic number

The atomic number indicates the number of protons that are present in the nucleus of an atom.

If the atom is electrically neutral, the positive charge of the protons is balanced by the negative charge of the electrons. That is, the number of protons in the nucleus is equal to the number of electrons in its orbitals, so that in a neutral atom the atomic number also indicates the number of electrons.

Mass number

The mass number indicates the total number of particles in the nucleus. That is, the mass number is the sum of the number of protons and the number of neutrons in the atomic nucleus.

Number of protons, neutrons and electrons in chlorine-35

The atomic number of chlorine is 17, while the mass number of chlorine-35 is 35.

So, being a neutral atom, by definition of atomic number the amount of protons and electrons that the isotope of chlorine has is 17.

Finally, knowing the number of protons and the atomic mass of the isotope, the number of neutrons is calculated by:

35 =17 + number of neutrons

35 - 17 = number of neutrons

18= number of neutrons

In summary, the number of protons and electrons of the isotope of chlorine named chlorine-35 is 17, while the number of neutrons is 18.
