A hydrocarbon X with formula 
consumes two moles of 
on catalytic hydrogenation of one mole. On ozonolysis, X gives two moles of ethanedial (glyoxal). The hydrocarbon X is:
Text Solution
Verified by ExpertsThe correct answer is:
B
using 
two 
-bonds (a diene). Ozonolysis of 1,4-cyclohexadiene cleaves both isolated double bonds symmetrically to give 2 mol glyoxal ( 
); 1,3-diene would give glyoxal + succinaldehyde, and the methylcyclopentadiene would not give glyoxal.
