The mechanism of SN1 reaction is given as :
`underset("pair")underset("Solvent Separated ion")(underset("lon pair")(R-X-R^(o+)X^(Theta)rarrR^(o+))"||"X^(Theta)overset(Y^(Theta))rarrR-Y+X^(Theta))`
A student writes general characteristics based on the given mechanism as :
(a) The reaction is favoured by weak nucleophiles.
(b) `R^(o+)` would be easily formed if the substituents are bulky.
(c) The reaction is accompanied by racemization.
Which observations are correct?

A

(A) and (B)

B

(A) and (C)

C

(A), (B) and (C)

D

(B) and (D)

Text Solution

Verified by Experts

The correct Answer is:
C
Above reaction is `S_(N^1)` reaction as it proceeds via formation of carbocation. Polar protic solvent is more suitable for `S_(N^1)` and racemisation takes place.
