question_answer 1)

  Hyper conjugation involves delocalization of : (a) electrons of carbon-hydrogen o bond of an alkyl group directly attached to an atom of unsaturated system (b) electrons of carbon-hydrogen o bond of alkyl group directly attached to the positively charged carbon atom (c) \[\pi \]-electrons of carbon-carbon bond (d) lone pair of electrons

Answer:

  (a, b) (C-H) \[\sigma \] bond at \[\alpha \]-position with respect to unsaturated   carbon or positively charged carbon is involved in hyper conjugation
