Question

The compound that will react most readily with gaseous bromine has the formula

• A. $C_4{H}_{10}$
• B. $C_2{H}_4$
• C. $C_3{H}_6$
• D. $C_2{H}_2$

Answer 1

The correct option is C $C_3{H}_6$

Bromine gas reacts with alkene to give allylic substituted product by free radical mechanism. And we know that reaction of free radical depends upon stability of free radical, which here will be stabilised by the conjugation with $\pi$ bond.
