An unsaturated hydrocarbon X absorbs two hydrogen molecules on catalytic hydrogenation, and also gives following reaction: X → ii Zn H 2 O i O 3 A → Ag NH 3 2 + B (3-oxo-hexanedicarboxylic acid) X will be:

Correct answer

2

Step-by-step solution

Since X absorb two molecules of hydrogen on cataytic hydrogenation, it shoulf have to two double bonds. Initial reaction is ozonolysis.
