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

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

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

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

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

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

h) The IUPAC name of the compound is 2-cyclopentenecarbonitrile

Step 1: Definition of IUPAC

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

Step 2: 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
