Step-by-step solution

IUPAC

The naming of a compound all over the world is given by IUPAC. Based on the position of the substituents, compounds possess different IUPAC names.

IUPAC rules 

The rules are stated as:

• Numbering is done in a way that the substituents are assigned the lowest number.
• The base name consists of the longest carbon chain and is mentioned at last.
• The substituents are named first in alphabetical order.

IUPAC naming of the given compounds 

a. The given compound is composed of five carbon atoms in a chain in which a chlorine atom and a methyl group are attached to C-3 and C-2, respectively.

Thus, the IUPAC name of the given compound is 3-chloro-2-methylpentane.

3-Chloro 2- methyle pentane

b. The given compound is composed of seven carbon atoms in a chain in which a bromine atom and two methyl groups are attached to C-2 and C-5, respectively.

Thus, the IUPAC name of the given compound is 2-bromo-5,5-dimethylheptane.

2-bromo-5,5-dimethyle heptane

c. The given compound is composed of six carbon atoms in a cyclic form in which a bromine atom and a methyl group are attached to C-1 and C-2, respectively.

Thus, the IUPAC name of the given compound is 1-bromo-2-methylcyclohexane.

1-bromo-2-methylcyclohexane

d. The given compound is composed of 10 carbon atoms in a chain in which an ethyl group, a fluorine atom, and an isopropyl group are attached to C-6, C-2, and C-7, respectively.

Thus, the IUPAC name of the given compound is 6-ethyl-2-fluoro-7-isopropyldecane.

6-ethyl-2-fluoro-7-isopropyldecane
