Question

Which of the following will not show geometrical isomerism?

Which of the following will not show geometrical isomerism?

• A.
• B.
• C.
• D.

Answer 1

The correct option is A

Analysing the given options:

$2,3$-Dimethylpent-$2$-ene will not show geometrical isomerism as it has two same groups $(-C{H}_3)$on the same carbon atom of the double bond.


According to $CIP$ priority rule when the higher priority group is on the same side of double bond is known as cis isomer and if it is opposite to each other is called trans isomer. Geometrical isomers are a type of stereoisomers. So, the following will exhibit cis and trans isomers as follows-

A)
B)
C)
Hence, option (D) is correct
