Question

Which of the following compounds exhibit geometrical isomerism?
Options
A 1-Pentene
B 2-Methyl-2-pentene
C 2-Pentene
Correct Answer
D 2-Methyl-2-butene
Correct Answer

Option C is the correct answer.

Detailed Explanation

2-Pentene (CH3CH=CHCH2CH3) shows geometrical isomerism because each carbon of the double bond has two different groups attached (cis/trans isomers exist). 1-Pentene has CH2 at one end, 2-methyl-2-pentene and 2-methyl-2-butene have identical groups on one carbon.

Hint

Which alkene has different groups on both carbons of the double bond?
