Solution

Chlor-alkali process is used for manufacturing sodium hydroxide which yields chlorine and hydrogen gases are formed as by-products.
$2 NaCl (aq) + 2 H_{2} O (l) \to 2 NaOH (aq) + {Cl}_{2} (g) + H_{2} (g)$

Chlorine gas on reaction with limewater produces bleaching powder. Bleaching powder is used as a bleaching agent in chemical industries.
$Ca {(OH)}_{2} (s) + {Cl}_{2} (g) \to {CaOCl}_{2} (s) + H_{2} O (l)$
Therefore, X is chlorine gas, and Y is bleaching powder.
