    Which of the following compounds will exhibit geometrical isomerism? [JEE Main Solved Paper-2015 ]

    A) 2-Phenyl-1-butene

    B) 1,1-Diphenyl-1-propane

    C) 1-Phenyl-2-butene

    D) 3-Phenyl-1-butene

    Correct Answer: C

    Solution :

    \[C{{H}_{2}}=\overset{\begin{smallmatrix}  Ph \\  | \end{smallmatrix}}{\mathop{C}}\,-C{{H}_{2}}-C{{H}_{3}}-\]not possible \[Ph-C{{H}_{2}}-CH=CH-C{{H}_{3}}\] Only exhibits geometrical isomrism.
