A C8H12 chiral hydrocarbon, X, is reduced by catalytic Hydrogenation to an achiral C8H14. Ozonolysis (Oxidative) of X gave a chiral C8H12O4 dicarboxylic acid. Choose X from the given. Attempt I first determined the chirality of the given alternatives. That rules out the 2nd option, as it is clearly symmetric. Then I just removed the double bonds, as asked in the question to see if any achiral hydrocarbon is formed. First one, I think is achiral. But I am not sure about the 3rd and 4th. How about my attempt and is it something that I am overlooking?
