Question

Match Column I with Column II with reference to types of reaction:

$\begin{array}{cccc}& \text{Column I}& & \text{Column II}\\ \text{A.}& \text{Ionization}\text{reaction}& \text{p.}& {\text{CH}}_4+2{\text{O}}_2\to {\text{CO}}_2+2{\text{H}}_2\text{O}\\ \text{B.}& \text{Dissociation}\text{reaction}& \text{q.}& {\text{H}}_2{\text{O}}_2\to {\text{H}}_2\text{O}+{\text{O}}_2\\ \text{C.}& \text{Decomposition}\text{reaction}& \text{r.}& \text{Mg}{\text{Cl}}_2\to {\text{Mg}}^{2+}+2{\text{Cl}}^{-}\\ \text{D.}& \text{Combustion}\text{reaction}& \text{s.}& {{\text{H}}_2\text{O}}_{\left(\text{basic}\right)}+{{\text{H}}_2\text{O}}_{\left(\text{acidic}\right)}\to {\text{H}}_3{\text{O}}^{+}+{\text{OH}}^{-}\end{array}$

• A. A $⟶$ s; B $⟶$ r; C $⟶$ q; D $⟶$ p
• B. A $⟶$ p; B $⟶$ s; C $⟶$ r; D $⟶$ q
• C. A $⟶$ s; B $⟶$ r; C $⟶$ q; D $⟶$ p
• D. A $⟶$ p; B $⟶$ s; C $⟶$ r; D $⟶$ q

Answer 1

The correct option is A

A $⟶$ s; B $⟶$ r; C $⟶$ q; D $⟶$ p

$\begin{array}{cc}\text{Column~I}& \text{Column~II}\\ \text{Ionization}\text{reaction}& {\text{H}}_2{\text{O}}_{\text{(basic)}}+{\text{H}}_2{\text{O}}_{\text{(acidic)}}\to {\text{H}}_3{\text{O}}^{+}+{\text{OH}}^{-}\\ \text{Dissociation}\text{reaction}& {\text{Mgcl}}_2\to {\text{Mg}}^{2+}+2{\text{Cl}}^{-}\\ \text{Decomposition}\text{reaction}& {\text{H}}_2{\text{O}}_2\to {\text{H}}_2{\text{O}}_2+{\text{O}}_2\\ \text{Combustion}\text{reaction}& {\text{CH}}_4+2{\text{O}}_2\to {\text{CO}}_2+2{\text{H}}_2\text{O}\end{array}$
From the table, it is clear
A $⟶$ s; B $⟶$ r; C $⟶$ q; D $⟶$ p
