Monochlorination of propane yields two constitutional isomers, and dichlorination yields four. trichlorination yields five constitutional isomers. draw all five trichloropropane isomers.

The trichloro isomers are [figure attached for structures]

a) 1,1,1-trichloropropane

b) 1,1,2-trichloropropane

c) 1,1,3-trichloropropane

d) 1,2,2-trichloropropane

e) 1,2,3-trichloropropane

Explanation:

Constitutional isomers are the compounds with same molecule formula but different arrangements of atoms on the chain.

The monochloro propane isomers are :

a) 1-chloropropane

b) 2-chloropropane

The dichloro isomers are :

a) 1,2-dichloropropane

b) 1,3-dichloropropane

c) 1,1-dichloropropane

d) 2,2-dichloropropane

The trichloro isomers are [figure attached for structures]

a) 1,1,1-trichloropropane

b) 1,1,2-trichloropropane

c) 1,1,3-trichloropropane

d) 1,2,2-trichloropropane

e) 1,2,3-trichloropropane
