Vedclass · Answer

(A) The free radical chlorination of alkanes is a chain reaction that often leads to a mixture of products due to polyhalogenation. To obtain the mono-substituted product $C_2H_5Cl$ in the best yield,it is necessary to minimize further chlorination. By taking an excess of ethane $(C_2H_6)$,the probability of a chlorine radical colliding with an ethane molecule is significantly higher than its collision with a $C_2H_5Cl$ molecule. Therefore,$C_2H_6 	ext{ (excess)} + Cl_2 \xrightarrow{UV}$ is the condition that favors the formation of $C_2H_5Cl$ as the major product.
