\end{array}$
$C.\,\,F -CH_2 -COOH$
$D.\,\,Br -CH_2-CH_2 -COOH$
Correct answer is
| $List-I$ | $List-II$ |
| $(A)$ $Cd ( s )+2 Ni ( OH )_{3}( s ) \rightarrow CdO ( s )+2 Ni ( OH )_{2}( s )+ H _{2} O (l)$ | $(I)$ Primary battery |
| $(B)$ $Zn ( Hg )+ HgO ( s ) \rightarrow ZnO ( s )+ Hg (l)$ | $(II)$ Discharging of secondary battery |
| $(C)$ $2 PbSO _{4}( s )+2 H _{2} O (l) \rightarrow Pb ( s )+ PbO _{2}( s )+ 2 H _{2} SO _{4}( aq )$ | $(III)$ Fuel cell |
| $(D)$ $2 H _{2}( g )+ O _{2}( g ) \quad \rightarrow 2 H _{2} O (l)$ | $(IV)$ Charging of secondary battery |
