The rate of Hofmann degradation is influenced by the nature of substituent, G. which of the following represents the correct decreasing rate of degradation with various substituents?

A

`-NO_2gt -Nlgt -Hgt -CH_3gt -OCH_3`

B

`-OCH_3gt -CH_2gt -Clgt - Hgt -NO_2`

C

`-OCH_3gt-CH_3gt-Hgt-Clgt -NO_2`

D

`-CH_3gt-Clgt-Hgt-OCH_3gt-NO_2`

Text Solution

Verified by Experts

The correct Answer is:
C
When the migratory group is aryl (as in the given case), the rate of degradation is increased by the presence of electron releasing substituents in the aromatic ring.
