Hydrocarbons - Result Question 34

####36. Correct order of stability is :

(a) cis -2-butene $>$ 1-butene $>$ trans -2-butene

(b) trans-2-butene $>$ cis-2-butene $>$ 1-butene

(d) cis-2-butene $>$ trans-2-butene $> 1$ -butene

Show Answer

Solution:

(b)CC=CC

Due to more hyper-conjugation in

$(6 α - H$ atoms) than in 1-butene ( $2 α - H$ atoms $)$ , the former is more stable.

In trans-2-butene, the two methyl groups are for apart. Hence, it is most stable.
