Q.64. Compound (X) is subjected to the sequence of reactions as shown above. Molar mass of the major product (Y) formed is ______ gmol⁻¹. (Given molar mass in g mol⁻¹ C : 12, H : 1, O : 16) [Figure: Reaction scheme starting with compound (X) which is 1,2-dibromoethane. Step (i) is Br₂/CHCl₃, which is incorrect as X is already dibromoethane. Let's assume X is styrene (vinyl benzene). Step (i) is Br₂/CHCl₃. Step (ii) is NaNH₂ (excess). Step (iii) is CH₃I. Step (iv) is H₂, Na/NH₃ (l). The final product is (Y).] Let's re-interpret the starting material and reactions based on the solution provided. The solution shows a reaction starting with styrene (Ph-CH=CH₂). Let's assume X is styrene.
