Question 4.22: One mole of the Compound (A), C8H12 incapable of showing st......

One mole of the Compound (A), C_8H_{12} incapable of showing stereoisomerism, reacts with only one mole of H_2 on hydrogenation over Pd. It undergoes ozonolysis to give a symmetrical diketone (B), C_8H_{12}O_2. What are the structures of (A) and (B)?

Since, Compound (A), C_8H_{12}, on ozonolysis gives only one symmetrical diketone (B), C_8H_{12}O_2, with the same number of carbon atoms and also since (A) consumes only one mole of hydrogen, the structures of (A) and (B) are as follows.
