• # question_answer Condition for maximum yield of ${{C}_{2}}{{H}_{5}}Cl$ is   [IIT-JEE 1986] A) ${{C}_{2}}{{H}_{6}}$ (excess) $+C{{l}_{2}}\xrightarrow{UV\text{ Light}}$ B) ${{C}_{2}}{{H}_{6}}$ + $C{{l}_{2}}\underset{\text{ Room}\,\text{temp}\text{.}}{\mathop{\xrightarrow{\text{Dark}}}}\,$ C) ${{C}_{2}}{{H}_{6}}+C{{l}_{2}}\text{ (excess) }\xrightarrow{UV\text{ Light}}$ D) ${{C}_{2}}{{H}_{6}}+C{{l}_{2}}\xrightarrow{UV\text{ Light}}$

${{C}_{2}}{{H}_{6}}(\text{excess)}+C{{l}_{2}}\xrightarrow{U.V.\text{Light}}\underset{\text{(Major product)}}{\mathop{\underset{\text{Ethyl chloride}}{\mathop{{{C}_{2}}{{H}_{5}}Cl}}\,}}\,+HCl$
