Chemistry Question on Alkenes

The most reactive alkene HBrHBr among the following is

A

(CH3)2C=C(CH3)2(CH_3)_2C=C(CH_3)_2

B

CH2=CH2CH_2=CH_2

C

(CH3)2C=CH2(CH_3)_2C=CH_2

D

CH3CH=CHCH3CH_3CH=CHCH_3

Answer

(CH3)2C=C(CH3)2(CH_3)_2C=C(CH_3)_2

Explanation

Solution

(CH3)2C=C(CH3)2(CH_3)_2C = C(CH_3)_2 has the least heat of hydrogenation and also forms most stable 33^{\circ} carbocation.
