question_answer 1)

  Which of the following compounds will not exist as resonance hybrid? Give reason for your answer : (i) \[C{{H}_{3}}OH\]        (ii) \[R-CON{{H}_{2}}\]                   (iii) \[C{{H}_{3}}CH=CHC{{H}_{2}}N{{H}_{2}}\]

Answer:

  \[C{{H}_{3}}-\underset{\centerdot \centerdot }{\overset{\centerdot \centerdot }{\mathop{O}}}\,-H\]does not contain Ti-electrons and hence will not be regarded as a resonance hybrid.
