Question
Which of the following compounds exhibit geometrical isomerism?
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?
