Step-by-step solution

Definition of IUPAC

An acronym for the International Union of Pure and Applied Chemistry is IUPAC

Explanations

a) The acid has six carbon straight chain in which contains two carboxyl groups on$C_2 and C_5$

The IUPAC name of the compound is 2,5-dimethyl hexane dioic acid.

b) The acid has three carbon straight chains with two methyl groups on$C_2$

The IUPAC name of the compound is 2,2-dimethylpropanoic acid.

c) The structure of the compound indicates that it is a benzoic acid derivative with a cyano group in the meta position

The IUPAC name of the compound is meta-cyanobenzoic acid.

d) The structure of the compound shows that it is cyclic with a ring made u of ten carbon atoms having a carboxyl group and has a double bond between$C_2 and C_3$ It has groups of similar priorities on the opposite sides of the double bond, It is an E isomer

The IUPAC name of the compound is (E)-cyclodec-2-enecarboxylic acid.

e) The structure of the compound shows that it is a nitrile with a three-carbon straight-chain and has to methyl groups on$C_2$

The IUPAC name of the compound is 2,2-dimethylpropanenitrile

f) The name of the compound shows that it is a carboxylic acid with a six-carbon straight-chain and has an ethyl group on$c_3$

The IUPAC name of the compound is 3-ethyl hexanoic acid

g) The name of the compound shows that it is a carboxylic acid with a five-carbon straight-chain and has two bromine atoms, one on $C_4 and other on C_5$

The IUPAC name of the compound is 4, 5 dibromopentanoic acid

h) The name of the compound shows that it is a nitrile with a cyclopentene ring having a double bond between$C_2 and C_3$

The IUPAC name of the compound is 2-cyclopentenecarbonitrile
