Identify the allylic hydrogens in

(a) Cyclohexene

(b) 1-Methylcyclohexene

 (c) 2,3,3-Trimethyl-1-butene

 (d) 1-Octene

Sample Solution (a) Allylic hydrogens are bonded to an allylic carbon. An allylic carbon is an sp3-hybridized carbon that is attached directly to an sp2-hybridized carbon of an alkene. Cyclohexene has four allylic hydrogens.
