Question

which member of the following pair would undergo a faster Sn1 reaction? explain. ​

Answer 1

FUNCTIONAL groups at Ortho positions -Ortho benzene would undergo faster Sn1 reaction

Answer 2

Hey dear,

● Answer -
1st compound => 1-bromocyclohexene

● Explanation -
- Speed of SN1 reaction depends on stability of carbocation.
- Stability of carbocation in decreasing order is 3° > 2° > 1°
- Carbocation of 1-bromocyclohexene is more stable (2° C-atom) than that of 2-bromocyclohexene (1° C-atom).
- Hence, 1-bromocyclohexene will give faster SN1 reaction.


Hope this helped...
