    Which of following are correct matched? [a] Position isomer of isopropyi alcohol \[C{{H}_{3}}-\underset{\begin{smallmatrix}  | \\  OH \end{smallmatrix}}{\mathop{CH}}\,-C{{H}_{3}}\] [b] Functional isomer of 1-butadiene \[C{{H}_{3}}-C\equiv C-C{{H}_{3}}\] [c] Position isomer of ethylidene chloride \[Cl-C{{H}_{2}}-C{{H}_{2}}-Cl\] [d] Metamer of ethyl acetate \[H-\underset{\begin{smallmatrix}  || \\  O \end{smallmatrix}}{\mathop{C}}\,-O-C{{H}_{2}}-C{{H}_{2}}C{{H}_{3}}\]

    A)  A, B            

    B)  B, C

    C)  C, D

    D)  A, D

    Correct Answer: C

    Solution :

     Position isomer of ethylidene chloride is ethylene dichloride \[\left( \underset{\begin{smallmatrix}  | \\  Cl \end{smallmatrix}}{\mathop{C{{H}_{2}}}}\,-\underset{\begin{smallmatrix}  | \\  Cl \end{smallmatrix}}{\mathop{C{{H}_{2}}}}\, \right)\]and propyl formate\[(HCOOC{{H}_{2}}C{{H}_{2}}C{{H}_{3}})\]is the metamer of ethyl acetate.
