Rank the following in order ofdecreasing rate in an `E_2` reaction :

A

`a gt b gt c`

B

`c gt a gt b`

C

`c gt b gt a`

D

`b gt a gt c`

Text Solution

Verified by Experts

The correct Answer is:
B
In `E_2` anti-elimination take place, H and bromine must be anti to each other (c) is most favourable because both hydrogen are anti to bromine most favourable for `E_2` reaction. (b) is least reactive because hydrogen and bromine both are on same side. (b) is inert toward `E_2` reaction.
