  • question_answer
    The shapes of methane, ethene and ethyne molecules are, respectively

    A) Tetrahedral, planar and linear

    B) Tetrahedral, linear and planar

    C) Pyramidal, planar and linear

    D) Tetrahedral, pyramidal and planar

    Correct Answer: D

    Solution :

    \[CH\equiv CH\xrightarrow{NaN{{H}_{2}}}CH\equiv {{C}^{-}}N{{a}^{+}}\underset{-NaI}{\mathop{\xrightarrow{C{{H}_{3}}I}}}\,CH\equiv C-C{{H}_{3}}\] \[\underset{\text{Pent}-\text{2}-\text{yne}}{\mathop{{{C}_{2}}{{H}_{5}}-C\equiv C-C{{H}_{3}}}}\,\underset{-NaI}{\mathop{\xleftarrow{{{C}_{2}}{{H}_{5}}I}}}\,N{{a}^{+}}\,{{C}^{-}}\equiv C-C{{H}_{3}}\]
