f.  The IUPAC name of the compound is 3-ethylhexanoic 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 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  

The IUPAC name of the compound is 2,5-dimethylhexanedioic acid.

b.  The acid has three carbon straight chain with two methyl groups on 

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-cyano benzoic 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 It has groups of similar priorities on the opposite sides of the double bond, It is a 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 

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 

The IUPAC name of the compound is 3-ethylhexanoic 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   

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  

 The IUPAC name of the compound is 2-cyclopentenecarbonitrile
