A) propene
B) 1-butene
C) but-2-ene
D) pent-2-ene
Correct Answer: C
Solution :
Anti-Markownikoffs rule is not applicable case of symmetrical alkenes. The structures of the given compounds are \[\underset{\text{propene}}{\mathop{C{{H}_{3}}CH=C{{H}_{2}}}}\,\]\[\underset{1-\text{butene}}{\mathop{C{{H}_{3}}C{{H}_{2}}CH=C{{H}_{2}}}}\,\] \[\underset{\begin{smallmatrix} \text{but}-2-\text{ene} \\ (symmetrical) \end{smallmatrix}}{\mathop{C{{H}_{3}}CH=CHC{{H}_{3}}}}\,\]\[\underset{\text{pent}-2-\text{ene}}{\mathop{C{{H}_{3}}C{{H}_{2}}CH=CHC{{H}_{3}}}}\,\] Thus, anti-Markownikoffs rule is not applicable to but-2-ene.
