A) \[{{C}_{2}}{{H}_{6}}\]
B) \[{{C}_{2}}{{H}_{5}}Cl\]
C) \[{{C}_{2}}{{H}_{5}}OH\]
D) \[{{C}_{2}}{{H}_{5}}CN\]
Correct Answer: B
Solution :
\[{{\text{C}}_{\text{2}}}{{\text{H}}_{\text{5}}}\text{Cl}\]can give Grignard reagent when reacted with Mg in dry ether. \[RX+Mg(dry)\xrightarrow{\text{Dry}\,\text{ether}}RMgX\] \[{{C}_{2}}{{H}_{5}}Cl+Mg\underset{\,\,\,\,\,\,\,\,\,\,\,\,\,\text{Ethyl}\,\text{magneslum}\,\text{chloride}}{\mathop{\xrightarrow{\text{Dry}\,\text{ether}}{{C}_{2}}{{H}_{5}}MgCl}}\,\]
