$NF_3, NCl_3$

Vedclass · Answer

(A) $NF_3$ undergoes hydrolysis via the $S_N^1$ mechanism because the $N-F$ bond is strong and the lone pair on $N$ is not easily available for nucleophilic attack,requiring a dissociative pathway.$NCl_3$ undergoes hydrolysis via the $S_N^2$ mechanism because the $Cl$ atoms are larger and the $N-Cl$ bond is more polarizable,allowing for an associative pathway with water.Therefore,the correct pair is $NF_3$ and $NCl_3$.

In which of the following compounds does hydrolysis take place through $S_N^1$ and $S_N^2$ mechanisms respectively?
