Chemistry Question on Organic Chemistry- Some Basic Principles and Techniques

Which of the following alkcnes is the most stable ?

A

CH3CH=CHCH3CH_3CH=CHCH_3

B

(CH3)2C−CH2(CH_3)_2C-CH_2

C

(CH3)2C=CHCH3(CH_3)_2C=CHCH_3

D

(CH3)2C=C(CH3)2(CH_3)_2C =C(CH_3)_{2}

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 is most stable. It is due to maximum hyperconjugation. It has 1212 hyperconjugative structures.
