An alkene (X) on ozonolysis followed by reduction gives following products: H-CHO ( 2 moles), H-CO-CO-CHO , CH₃-CO-CO-CH₃ . The alkene (X) is:

Step-by-step solution

Ozonolysis (followed by reductive workup with Zn/H₂O ) cleaves C=C bonds and converts each alkene carbon into a carbonyl. We can reverse-engineer the parent alkene from the fragments obtained. Analysing the products: HCHO(2 moles ) : Two equivalents of formaldehyde indicate the presence of two terminal or exocyclic =CH₂ groups in the parent molecule. CH₃-CO-CO-CH₃ (biacetyl): To get this discrete fragment, the parent alkene must contain the structural unit -C(CH₃)=C(CH₃)- , i.e., an endocyclic double bond in which
