Chemistry Question on Organic Chemistry- Some Basic Principles and Techniques

Which of the following compounds will exhibit geometrical isomerism?

A

1-Phenyl-2-butane

B

3-Phenyl-1-butene

C

2-Phenyl-1-butene

D

1,1-Diphenyl-1-propene

Answer

1-Phenyl-2-butane

Explanation

Solution

Only compound 1-phenyl-2-butene can show geometrical isomerism.

(a) 3-phenyl-1-butene

undefinedundefined

(No geometrical isomerism)

(b) 2-phenyl-1-butene

(No geometrical isomerism)

(c) 1,1, diphenyl-1-propene

(No geometrical isomerism)

(d) 1-phenyl-2-butene :

CH43−HC3=C1H−CH21−phC \overset{4}{H}_{3}-H\overset{3}{C}= \overset{1}{C}H-C\overset{1}{H_{2}}-ph

The correct possible answer is (d) but due printing mistake. No answer is correct.
