, Rate of reaction toward Backmann rearrangement when `gamma=underset((i))(CH_(3)CO_(2)^(-)), underset((ii)) (Cl-CH_(2)-CO_(2)^(-)), underset((iii)) (Ph-SO_(3)^(-))`
A
`(i) gt (ii) gt (iii)`
B
`(ii) gt (i) gt (iii)`
C
`(iii) gt (ii) gt (i)`
D
`(iii) gt (i) gt (ii)`
Text Solution
Verified by Experts
The correct Answer is:
C
Since RDS involve removal of leaving group, rate of reactions compared commpared by leaving group tendency. `Ph-SO_(3)^("Ө") gt Cl-CH-(2)-CO_(2)^("Ө") gt CH_(3)-CO_(2)^("Ө")` (weak base good leaving group)
