Question
The reaction is described as
The reaction is described as
A.
$${S_E}2$$
B.
$${S_N}1$$
C.
$${S_N}2$$
D.
$${S_N}0$$
Answer :
$${S_N}2$$
Solution :
When the attack of nucleophile takes place on the opposite side of the leaving group in the substrate molecule, a transition state is obtained. It is partially bonded to both the attacking nucleophile and the leaving group and results in the formation of product. Such reactions are called as $${S_N}2$$ ( bimolecular nucleophilic substitution reaction ) because in such reactions, rate depends on the concentration of both, the substrate and the nucleophile.
