Vedclass · Answer

(C) $1$. Combination reaction: $CH_{4(g)} + 2O_{2(g)} \xrightarrow{\Delta} CO_{2(g)} + 2H_2O_{(l)}$ (This is a combustion reaction,which is a type of combination/redox process where elements combine with oxygen).$2$. Decomposition reaction: $2H_2O_{(l)} \xrightarrow{	ext{electrolysis}} 2H_{2(g)} + O_{2(g)}$ ($A$ single compound breaks down into simpler substances).$3$. Displacement reaction: $Cl_{2(g)} + 2Br^-_{(aq)} ightarrow 2Cl^-_{(aq)} + Br_{2(l)}$ ($A$ more reactive halogen displaces a less reactive one).$4$. Disproportionation reaction: $2H_2O_{2(aq)} ightarrow 2H_2O_{(l)} + O_{2(g)}$ (The oxygen atom in $H_2O_2$ is simultaneously oxidized and reduced).Therefore,the correct match is $a-iii, b-iv, c-i, d-ii$.

List-$I$ (Types of redox reactions)	List-$II$ (Examples)
$a.$ Combination reaction	$(i)$ $Cl_{2(g)} + 2Br^-_{(aq)} \rightarrow 2Cl^-_{(aq)} + Br_{2(l)}$
$b.$ Decomposition reaction	$(ii)$ $2H_2O_{2(aq)} \rightarrow 2H_2O_{(l)} + O_{2(g)}$
$c.$ Displacement reaction	$(iii)$ $CH_{4(g)} + 2O_{2(g)} \xrightarrow{\Delta} CO_{2(g)} + 2H_2O_{(l)}$
$d.$ Disproportionation reaction	$(iv)$ $2H_2O_{(l)} \xrightarrow{\text{electrolysis}} 2H_{2(g)} + O_{2(g)}$
