JEE PYQ: General Organic Chemistry Question 25
Question 25 - 2020 (06 Sep Shift 1)
Which of the following compounds shows geometrical isomerism?
(1) 2-methylpent-2-ene
(2) 4-methylpent-2-ene
(3) 4-methylpent-1-ene
(4) 2-methylpent-1-ene
Show Answer
Answer: (2)
Solution
4-Methylpent-2-ene: $\text{CH}_3\text{CH}=\text{CH}-\text{CH}(\text{CH}_3)_2$. It has different groups on both carbons of the double bond, so it shows geometrical (cis-trans) isomerism.
