A liquid `(X)` having a molecular formula `C_(6) H_(12) O_(2)` is hydrolysed with water in the presence of an acid to give a carboxylic acid `(Y)` and an alcohol `(Z)`. Oxidation of `(Z)` with chrome acid gives `(Y)` . What are the structures of `(X), (Y)`, and `(Z)` ?

Explanation

`(X)` is an ester since on hydrolysis it gives acid `(Y)` and alcohol `(Z)` . Oxidation of `(Z)` gives `(Y)`. It suggests, `(Z)` is `1^@ RCH_2 OH`.
Reaction :
.
