Question: Which of the following compounds will show geometrical isomerism [IIT-JEE 1998]
Options:
A) 2-butene
B) Propene
C) 1-phenylpropene
D) 2-methyl-2-butene
Show Answer
Answer:
Correct Answer: A
Solution:
2-butene $ \underset{\text{(cis)}}{\mathop{\begin{matrix} \begin{matrix} , \\ CH_3-\underset{|}{\mathop{C}},=\underset{|}{\mathop{C}},-C_6H_5 \\ \end{matrix} \\ H,H \\ \end{matrix}}}, $ and $ \underset{\text{(Trans)}}{\mathop{CH_3-\underset{H}{\mathop{\underset{/}{\mathop{C}},}},=\overset{,H}{\mathop{\overset{/}{\mathop{C}},}},-C_6H_5}}, $
