Solution

Column I Column II

(A) Electrolysis of water produces (V) hydrogen and oxygen

(B) Lithium aluminium hydride is used as (IV) reducing agent

(C) Hydrogen chloride is a (II) polar molecule

(D) Heavy water is used in (I) atomic reactor

(E) Atomic hydrogen (II) recombines on metal surface to generate high temperature

$(A)$ Electrolysis of water produces hydrogen and oxygen as shown below::

$H_{2} O (l) \to H_{2} (g) + O_{2} (g)$
$(B)$ Lithium aluminium hydride $(L i A l H_{4})$ is used as a strong reducing agent and it reduces compounds containing $C = O$ functional group to corresponding alcohols.
$(C)$ Hydrogen Chloride is a polar molecule because the electronegativity of chlorine is greater than that of Hydrogen and thus the dipole moment of $H C l$ is non-zero.

$(D)$ Heavy water $(D_{2} O)$ is used as a moderator in atomic reactors.

$(E)$ Atomic hydrogen recombines on metal surfaces to generate high temperatures.
