f. 3-tert-butyl-2-ethyltoluene

Step-by-step solution

Step-by-Step Solution  Step 1: Structures from IUPAC name

The name before ‘benzene’ suggests the groups attached to the benzene ring.

Prefix o, m, and p before the name denote the positions of two groups in the disubstituted ring.

Name of the compounds ending in common names other than benzene contains the monosubstituted derivative of benzene.

Structures of the compound

a. isobutyl benzene

benzene ring substituted with an isopropyl group.

isobutyl benzene

b. o-dichlorobenzene

o suggests the two chloro groups at 1^st and 2^nd position.

o-dichlorobenzene

c. cis-1,2-diphenylcyclohexane

cis - two phenyl groups on the same side of the plane.

cis-1,2-diphenylcyclohexane

d. m-bromoaniline

aniline - nitrogen containing derivative of benzene.

m-bromoaniline

e. 4-chloro-1,2-diethylbenzene.

4-chloro-1,2-diethylbenzene

f. 3-tert-butyl-2-ethyltoluene

Toluene - benzene ring with a methyl group.

3-tert-butyl-2-ethyltoluene
