The leaving group is that functional group which is ejected with electrons of the o-bond in a reaction. Bette the leaving group, faster is the reaction. The relative leaving abilitiy of the leaving group X in (R-X) is increased by:
i. The polarisability of (R-X) bond ii. The degree of stabilisation through solvation of X.
iii. The strength of (R-X) bond. iv. The stability of `X^(Theta)`.
The leaving group tendency is also called fugacity.
Which statement is correct?

Options

A. Only `S_N1` reaction depends on the nature of leaving group.
B. Only `S_N2` reaction depends on the nature of leaving group.
C. Both `S_N1 and S_N2` reactions depend on the nature of leaving group.
D. All

Answer

C

Explanation

Both `S_N1 and S_N2` reactions depend on the nature of leaving group.
