  • question_answer Number of unhybridised orbitals in vinyl acetylene are [RPMT 1999]

    A) 2

    B) 3

    C) 4

    D) 6

    Correct Answer: D

    Solution :

               Vinyl acetylene there are 6 unhybridised orbitals. \[\underset{\text{(no}\text{. of unhybridised orbitals)}}{\mathop{\underset{\underset{1}{\mathop{\text{s}{{\text{p}}^{2}}}}\,}{\mathop{C{{H}_{2}}}}\,=\underset{\underset{1}{\mathop{\text{s}{{\text{p}}^{2}}}}\,}{\mathop{CH}}\,-\underset{\underset{\text{2}}{\mathop{\text{sp}}}\,}{\mathop{C}}\,\equiv \underset{\underset{\text{2}}{\mathop{\text{sp}}}\,}{\mathop{CH}}\,}}\,\]
