Question

Which of the following compounds will exhibit geometrical isomerism ?(a) 2 - Phenyl -1 - butene(b) 1, 1 - Diphenyl - 1 - propene(c) 1 - Phenyl - 2 - butene(d) 3 - Phenyl -1 - butene

Answer 1

d) 1-phenyl I hope this will help you plz mark me as brainliest

Answer 2

Answer:

(c) 1 - Phenyl - 2 - butene is the correct answer.

Explanation:

Geometrical isomerism is also called as EZ isomerism.

It is also known as cis trans isomerism.

2 compunds are said to be geometrically isomeric when they have same molecular formula but different geometrical symmetry.

For geometrical isomerism to happen there should be restricted rotation.

Also there should be a double bond.

There should be two different compunds on left hand side and right hand side.

c) 1 - Phenyl - 2 - butene

This compund has a carbon double bond.

It has 2 different groups on the left hand side and the right hand side.

It has restricted rotation.

Thus this compund shoes geometrical isomerism.

Hence, (c) 1 - Phenyl - 2 - butene is the is the correct answer.
