The compound which have higher no of pi bond will have higher HOH in case of same pi bond the Alkene which is less stable will give more HOH(heat of hydrogenation). So correct option is (3). Alpha hydrogen are that which are attached to canon next to sp² hybridised carbon atom.Hope it clears. If u have doubts then please clearify. And if u like my answer then please approve answer
