Problem 17.4 - Organic Chemistry

Question

Draw the structure corresponding to each name

1. isobutyl benzene 
2. o-dichlorobenzene 
3. cis-1,2-diphenylcyclohexane 
4. m-bromoaniline
5. 4-chloro-1,2-diethylbenzene  
6. 3-tert-butyl-2-ethyltoluene

Step-by-Step Solution

Answer

Answer

a. Isobutyl benzene

b) o-dichlorobenzene 

c. cis-1,2-diphenylcyclohexane 

d. m-bromoaniline 

e) 4-chloro-1,2-diethylbenzene 

f. 3-tert-butyl-2-ethyltoluene

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.

Step 2: 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
