I came across this question regarding hydrogenation of alkenes
Reaction A and Reaction B were carried out using the two different substrates as shown I have depicted how i thought the reaction would occur.This gives me the correct answer for Reaction A but not for Reaction B.
Apparently instead of b,the compound c would be formed,implying simple hydrogenation of the exocyclic bonds without the formation of a transition state as in reaction a .
I cannot figure out the exact cause for this. Does this have anything to do with the two double bonds being on the opposite sides in coumpound Y ,and therefore not being able to form the same transition state as X?
P.S: No catalysts were mentioned.Only H2(1 mole) and heat were mentioned in the original question.
