AIPMT PRELIMS 2000 Chemistry Alkenes MCQ Question

Type: MCQ-conceptual-Medium-Class 11

Correct order of stability is:

A

$¹⁻butene > Trans^{-2}-butene > Cis^{-2}-butene$

B

$Trans^{-2}-butene >¹⁻butene > Cis^{-2}-butene$

C

$Trans^{-2}-butene > Cis^{-2}-butene >¹⁻butene$

D

$Cis^{-2}-butene > Trans^{-2}-butene >¹⁻butene$

Correct Answer

Option C

Detailed Explanation

Tran $s^{-2}$ -butene is more stable than ci $s^{-2}$ -butene due to less steric hindrance, and both are more stable than¹⁻butene.
