Name the following hydrocarbon:
CH3CH2CH2CH2F
A. 4-fluorobutane
B. 2-fluorobutane
C. 1-fluorobutane
D. 1-fluoropentane
Answer:
The correct answer is (C)
Which is "1-fluorobutane"
Explanation:
Hope this helped if so please leave a "Rating" and "Like" and MARK me Brainliest if it was the BEST answer! THANKS! :)
The name of the hydrocarbon CH3CH2CH2CH2F is 1-fluorobutane.
In naming organic hydrocarbons, we count the number of the parent chain family. Here, we have an alkane with 4 carbons, which means that the parent chain is a family of alkane. The fourth compound in the family of an alkane is butane.
Afterwards, we will determine if there is any substituent attached to any of the carbon atoms in the chain and rank them in a way such that we have the lowest possible number.
Here, the fluorine is attached to the first carbon atom. So, it becomes 1-fluorobutane.

B
125 cm3
C
30 cm3
Answer: B. [tex]125\ cm^3[/tex].
The volume of the given object = [tex]125\ cm^3[/tex]
Explanation:
Given : Dimensions of an object : 5 cm x 5 cm x 5 cm [ it is a cube with all equal sides]
Formula to find the volume of a cube = [tex](side)^3[/tex]
[tex]=5^3\ cm^3=125\ cm^3[/tex]
Hence, the volume of the given object = [tex]125\ cm^3[/tex]
Therefore , the correct option is B. [tex]125\ cm^3[/tex].

What is 797 mm hg to atm?
Answer:
797 mm hg = 1.04868 atm
Explanation:
1 atm = 760 mm hg
797 mm hg to atm is 1.0468 atm
Pressure is defined as the physical force exerted on an object. The force applied is perpendicular to the surface of objects per unit area.
There are many different types of units and prefixes that may be used in general practice to reflect pressure. Thus, it is ensured that all the measurements and their respective units are in the same framework when conducting pressure calculations.
Pascal is the SI unit of pressure, and is the basic pressure unit in the SI (the International System of Units) system.
Given,
Pressure = 797 atm
1 mm Hg = 0.00131579 atm
797 mm Hg = 0.00131579 × 797
= 1.04868 atm

dipole dipole bonds are covalent bond?
Answer:
The polar covalent bond is much stronger in strength than the dipole-dipole interaction. The former is termed an intramolecular attraction while the latter is termed an intermolecular attraction. So now we can define the two forces: Intramolecular forces are the forces that hold atoms together within a molecule.
Explanation:
I have some things to point out:
#1: There is no such thing as "Dipole-dipole bonds", only Dipole-dipole interactions between molecules that share an unequal balance of electrons between their atoms.
#2: Intermolecular forces of attraction such as Dipole-dipole interactions are not considered as covalent bonds. Covalent bonds are rigid and are considered intramolecular forces of attraction (found within the molecule instead of between)

how dose dissolving sugar in water show that matter is made up of particles
Answer:
When sugar dissolves, the sugar particles separate from each other and mix with the water particles. When the sugar particles separate, the smaller water particles fit into the spaces between the larger sugar particles. The water and sugar particles are attracted to each other, so they move closer together when they mix.

Answer: Metallic Bonding.In metallic bonds, the valence electrons from the s and p orbitals of the interacting metal atoms delocalize. That is to say, instead of orbiting their respective metal atoms, they form a “sea” of electrons that surrounds the positively charged atomic nuclei of the interacting metal ions.

The atomic number of this atom : 8
Further explanationGiven
Atomic model (attached)
Required
The atomic number
Solution
To determine the atomic number of an element, we can look at the number of electrons or the number of protons, because
atomic number = number of protons = number of electrons in neutral atoms
While the mass number is the number of neutrons + the number of protons located in the atomic nucleus
The charge of each of these atomic sub particles:
electron: charge -1proton: charge +1neutron: not charged / 0If we look at this atomic model, there are 8 electrons in the shell, consisting of 2 electrons in the first shell and 6 electrons in the second shell (which can also be called valence electrons)
Whereas in the atomic nucleus there are 8 protons and 10 neutrons
