Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
The lone pair electrons on $N$ atoms in $A g N O_{2}$ attacks $C_{2} H_{5} B r$ to form nitroethane as the major product. In $N O_{2}$ both $N$ and $O$ can attack to form compounds as both have a lone pair of electrons.
