Identify the aldehyde from following so that the aldehydic group is NOT attached with any sp^3 hybrid 'c' atom.

Options

  1. AMethanal
  2. BEthanal
  3. C2-Methyl Propanal
  4. DPropanal

Correct answer

A. Methanal

Step-by-step solution

Methanal is H-CHO . The aldehydic group ( -CHO ) is attached to a hydrogen atom, not to any carbon atom. Therefore, it is not attached to any sp^3 hybridized carbon atom. Ethanal is CH₃-CHO . The -CHO group is attached to a methyl group, which contains an sp^3 hybridized carbon atom. 2-Methylpropanal is (CH₃)₂CH-CHO . The -CHO group is attached to a CH group, which is an sp^3 hybridized carbon atom. Propanal is CH₃-CH₂-CHO . The -CHO group is attached to a CH₂ group, which is an sp^3 hybridized carbon atom. Thus, m
