Question

In which of the following reactions, ethyl chloride is obtained in good yield?

• A. Ethane $+ Cl _{2} \xrightarrow{ hv }$
• B. Ethane $+ Cl _{2}($ excess $) \xrightarrow{\text { hv}} $
• C. Ethene $+ Cl _{2} \xrightarrow{\text { in dark }}$
• D. Benzene $+ Cl _{2} \longrightarrow$

Answer 1

Answer: (A)

Ethane and limited quantity of chlorine reacts in presence of sunlight to form ethyl chloride. Whereas in presence of excess chlorine, hexa-chloro ethane (artificial camphor) is obtained.
$C _{2} H _{6}+ Cl _{2} \xrightarrow{ hv } C _{2} H _{5} Cl + HCl$
