उत्तर १
Ethene adds a molecule of water in the presence of mineral acids to form ethyl alcohol.
\[\ce{CH2 = CH2 + H2O ->[H+] CH3 - CH2 - OH}\]
उत्तर २
\[\ce{\underset{ethene}{CH2 = CH2} + H2SO4 -> \underset{hydrogen sulphate}{\underset{ethyl}{C2H5HSO4}} -> \underset{ethanol}{C2H5OH} + \underset{Sulphuric acid}{H2SO4}}\]

Raina while doing certain reactions observed that heating of substance ‘X’ with a vinegar-like smell with a substance ‘Y’ (which is used as an industrial solvent.) in the presence of conc. Sulphuric acid in a water bath gives a sweet-smelling liquid ‘Z’ having molecular formula C4H8O2. When heated with caustic soda (NaOH), ‘Z’ gives back the sodium salt and the compound ‘Y’.
Identify ‘X’, ‘Y’, and ‘Z’. Illustrate the changes with the help of suitable chemical equations.
