starting with cyclohexene, propose a reasonable synthesis of the cyclohexene derivative. the starting material is a 6 carbon ring with a double bond between carbons 1 and 2. in four steps, this is transformed to a 6 carbon ring with a double bond between carbons 1 and 2 with a substituent on carbon 3. the substituent is a carbon bonded to two methyl groups and a hydroxy group.

Answers

Answer 1

Starting with cyclohexene, a reasonable synthesis of the cyclohexene derivative would include the following four steps:

Step 1: Oxymercuration-demercuration

When cyclohexene is treated with mercury(II) acetate (Me2Cu) in the presence of an alcohol (such as methanol) in a polar aprotic solvent such as acetone, a cyclohexene derivative with a hydroxyl group on carbon 3 is formed.

Because this is a reversible reaction, the product can be isolated in large quantities by removing the mercury ion.

Step 2: Alkylation

Step 1 alcohol is then alkylated with methyl iodide (CH3I) in the presence of a base (such as sodium hydroxide) to yield a cyclohexene derivative with a methyl group on carbon 3.

Step 3: Alkylation

Step 2 results in a cyclohexene derivative with two methyl groups on carbon 3 that is alkylated again with methyl iodide (CH3I) in the presence of a base (such as sodium hydroxide).

Step 4: oxidation

To convert the alcohol on carbon 3 to a carboxylic acid, the product from step 3 is oxidized with an oxidizing agent such as pyridinium chlorochromate (PCC) or Jones reagent.

The end result is a 6-carbon ring with a double bond between carbons 1 and 2 and a substituent on carbon 3, which is a carbon bonded to two methyl groups and a hydroxy group.

What types of bonds are present in an ionic compound that contains a polyatomic ion?

Answers

Answer:

In Explanation

Explanation:

An ionic compound that contains a polyatomic ion is a chemical compound made up of two or more ions that are held together by ionic bonds. Ionic bonds form when one or more electrons are transferred from one atom to another, creating ions with a positive or negative charge. In the case of an ionic compound that contains a polyatomic ion, the compound will contain at least one ion made up of more than one atom. These ions are called polyatomic ions and they have a net electrical charge. The ionic compound will be held together by the electrostatic attraction between the positive and negative ions.

A proton is a stable subatomic particle with a positive charge equal to one electron charge and a rest mass of 1.67262 1027 kg, or 1,836 times the mass of an electron.

Except for the hydrogen nucleus, all atomic nuclei are composed of protons and neutrons, which are electrically neutral particles. Every chemical element's nucleus contains the same number of protons. This number specifies an element's atomic number and determines its position in the periodic table. An atom is electrically neutral when the number of protons in its nucleus equals the number of electrons orbiting it.

O The blue proton is more acidic because its conjugate base is less stable, with a negative charge on the more electronegative oxygen atom

Answers

"The blue proton is more acidic because its conjugate base is less stable, with a negative charge on the more electronegative oxygen atom." is the correct choice

The acidity of a proton depends on the stability of its conjugate base. The more stable the conjugate base, the less acidic the proton.

In this case, the blue proton is bonded to an oxygen atom, which is more electronegative than the carbon atom to which the red proton is bonded.

When the blue proton is removed, the resulting negative charge is delocalized onto the oxygen atom, which is more electronegative, therefore the conjugate base is less stable, making the blue proton more acidic.

Kc= ([tex][CO_{2} ]^{4}[/tex]×[tex][H_{2} O]^{6}[/tex])÷ ([tex][C_{2}H_{6} ]^{2}[/tex]×[tex][O_{2} ]^{7}[/tex])

Finally, the equilibrium molar concentration is  ([tex][CO_{2} ]^{4}[/tex]×[tex][H_{2} O]^{6}[/tex])÷ ([tex][C_{2}H_{6} ]^{2}[/tex]×[tex][O_{2} ]^{7}[/tex])

Plasma is an electrically charged state of matter that is created from superheating a gas. In a bottle containing plasma, there are 100 negatively charged ions and 96 positively charged ions. What is the charge of the bottle of plasma?
a. +4 Charge
b. +196 Charge
c. -196 Charge
d. -4 Charge

Answers

Answer:

-4

Explanation:

The charge of the bottle of plasma would be -4, because 100 negatively charged ions (-) have a total charge of -100, and 96 positively charged ions (+) have a total charge of 96. When you subtract -100 from 96, you get -4.

you are better at performing lab experiments, and your lab partner is better at writing lab reports. so the two of you agree that you will do all the experiments, and she will write up all the reports.

Answers

The correct answer for the question is there are gains from the trade.

What is the principle that is stated above?There are gains from trade, which is a principle that can be mutually beneficial to each other.Trade is the activity of economic stakeholders exchanging products or services to meet their demands.The surplus of benefits from trade is referred to as the gain from trade. The parties' demands are met by exchanging similar goods or services.The gains from the trade are described as someone’s strength in their fields being shared with others who have their own strengths. It can be linked with trade, in which the economic agents offer their products to each other.

How many hydrogen atoms are in : (NH,)CO,?

Answers

NH2CO is the chemical compound known as Formamide, it is a molecule that consists of one nitrogen atom, two hydrogen atoms, one carbon atom, and one oxygen atom. Therefore, the number of hydrogen atoms in NH2CO is 2.

According to the passage, which of the following compounds can the worker use to catalyze the cleavage of a triglyceride (base-catalysis)?
A) HCl (aq)
B) NaCl (aq)
C) NaOH (aq)
D) Na2SO4 (aq)

Answers

Option C: According to the passage, base-catalyzed triglyceride (ester) cleavage occurs. NaCl and Na2SO4 are salted, while HCl is an acid. Only NaOH is a base that can catalyze ester saponification.

In chemistry, an ester is a compound derived from an acid (organic or inorganic) in which at least one acidic hydrogen atom of that acid (H) is replaced by an organyl group (R). A carboxylic acid and alcohol substitution reaction is an example of ester formation. Glycerides are fatty acid esters of glycerol; they are important in biology because they are one of the main classes of lipids and make up the majority of animal fats and vegetable oils. Esters can be formed from oxoacids (for example, acetic acid, orthocarbonic acid, sulfuric acid, perchloric acid, nitric acid, and xanthic acid esters), but also from acids that do not contain oxygen (e.g. esters of thiocyanic acid, hydrogen chloride, trithiocarbonic acid, tricyanomethane).

The dating web site oollama requires its users to create profiles based on a survey in which they rate their interest (on a scale from 0 to 3) in five categories: physical fitness, music, spirituality, education, and alcohol consumption. a new oollama customer, erin o'shaughnessy, has reviewed the profiles of 40 prospective dates and classified whether she is interested in learning more about them. based on erin's classification of these 40 profiles, oollama has applied a logistic regression to predict erin's interest in other profiles that she has not yet viewed. the resulting logistic regression model is as follows: for the 40 profiles (observations) on which erin classified her interest, this logistic regression model generates that following probability of interested.
