Question

Correct order of reactivity towards elimination reaction (i) \( C _{6} H _{5} CH _{2} CH _{2}- Br \) (ii) \( CH _{3} CH _{2} CH _{2}- Br \) (iii) (iv) (1) i \( > \) ii \( > \) iii \( > \) iV (2) ii \( > \) i \( > \) iii \( > \) iv (3) iii \( > \) iv \( > \) i \( > \) ii (4) iii \( > \) iv \( > \) i \( > \) ii

Answer 1

More the number of β- substituents (alkyl groups), more stable alkene it will form on β- elimination and more will be the reactivity.

I>III>II>IV
