Question

Which of the following can give a Grignard reagent when reacted with magnesium in dry ether?

• A. $C_2{H}_6$
• B. $C_2{H}_{5}Cl$
• C. $C_2{H}_{5}OH$
• D. $C_2{H}_{5}CN$

Answer 1

The correct option is B $C_2{H}_{5}Cl$

When ethyl chloride reacts with magnesium metal in presence of dry ether, it gives ethyl magnesium chloride. (Grignard reagent)

$C_2{H}_{5}Cl+Mg\to C_2{H}_5-Mg-Cl$

Hence, option B is correct.
