Question
$S_N1$ reaction is favoured by:
✓
Answer
$S_N1$ mechanism proceeds through carbocation formation and as stability of carbocation increases, it favours $S_N1$ mechanism.
And as we add bulky group to carbon attached with halogen, carbocation formed will become more stable due to $+I$ effect of bulky alkyl group so it favours $S_N1$ mechanism.
