Show Answer

Answer:

Correct Answer: A

Solution:

$ C_2H_5Br+Ag-O-N=O\to \underset{\text{Nitro ethane}}{\mathop{C_2H_5-N\searrow //\begin{matrix} O \\ O \\ \end{matrix}}}+AgBr $

$ Ag-O-N=O $ is a covalent compound. Therefore, attack of nucleophile occurs through Nitrogen atom. Hence, nitroethane is formed.
