Question

The mechanism of $S_N{}^1$ reaction is given as :

A student writes general characteristics based on the given mechanism as :
(a) The reaction is favoured by weak nucleophiles
(b) $R^{\oplus }$ would be easily formed if the substituents are bulky
(c) The reaction is accompained by recemization
(d) The reaction is favoured by non-polar solvents.
Which observations are correct?

• A. b and d
• B. a and c
• C. a, b and c
• D. a and b

Answer 1

Answer: (C)

$S_N{}^1$ favours
(a) The reaction is favoured by weak nucleophiles
(b) $R^{\oplus }$ would be easily formed if the substituents are bulky
(c) The reaction is accompained by recemization
