Answer
Compound X is obtained from catalytic cracking of petroleum fractions. This process typically produces smaller hydrocarbons, including alkenes. Given the options, Compound X is most likely to be Propene, as it is a common product of catalytic cracking.

Answer
Compound Y is formed when Compound X (Propene) reacts with dilute sulfuric acid. This reaction leads to the formation of an alcohol through hydration of the alkene, resulting in Propan-1-ol as Compound Y.

Answer
Compound Z is produced from Compound Y (Propan-1-ol) when it reacts with concentrated sulfuric acid, undergoing a condensation reaction to form an ester. This reaction results in the production of Ethyl propanoate, making Compound Z.
