The number of carbonyl carbon in the product X is Propyne → Zn/H 2 O O 3 /CH 2 Cl 2 ,Δ X

Correct answer

2

Step-by-step solution

Ozonolysis of propyne results in the formation of 2 -oxopropanal which contains keto group and aldehyde ( - C H O ) group. Hence, 2 -oxopropanal contains two carbon atoms.
