Question

Identify the reagent(s) 'A' and condition(s) for the reaction.

(JEE MAIN 2021)

• A. $A=C{l}_2;UVlight$
• B. $A=HCl,ZnC{l}_2$
• C. $A=C{l}_2;dark,AnhydrousAlC{l}_3$
• D. $A=HCl$ ;$AnhydrousAlC{l}_3$

Answer 1

The correct option is A $A=C{l}_2;UVlight$

In presence of U.V. light, free radical substitution reaction occurs, at allylic position.

With all other reagents, $Cl$ will get add to the alkene.

Hence, option (b) is correct.
