Question

Match each of the reactions given in Column I with the corresponding product(s) given in Column II. $\begin{array}{cc}\text{Column I}& \text{Column II}\\ \text{a.}Cu+dil.HN{O}_3& \text{p.}\text{NO}\\ \text{b.}Cu+conc.HN{O}_3& \text{q.}N{O}_2\\ \text{c.}Zn+dil.HN{O}_3& \text{r.}{N}_{2}O\\ \text{d.}Zn+conc.HN{O}_3& \text{s.}Cu(N{O}_3{)}_2\\ & \text{t.}Zn(N{O}_3{)}_2\end{array}$

• A. $\text{a}-\text{p},\text{s}$
  $\text{b}-\text{q},\text{s}$
  $\text{c}-\text{r},\text{t}$
  $\text{d}-\text{q},\text{t}$
• B. $\text{a}-\text{q},\text{s}$
  $\text{b}-\text{p},\text{s}$
  $\text{c}-\text{p},\text{t}$
  $\text{d}-\text{q},\text{t}$
• C. $\text{a}-\text{q},\text{s}$
  $\text{b}-\text{q},\text{s}$
  $\text{c}-\text{p},\text{t}$
  $\text{d}-\text{p},\text{t}$
• D. $\text{a}-\text{p},\text{s}$
  $\text{b}-\text{p},\text{s}$
  $\text{c}-\text{q},\text{t}$
  $\text{d}-\text{r},\text{t}$

Answer 1

The correct option is A $\text{a}-\text{p},\text{s}$

$\text{b}-\text{q},\text{s}$
$\text{c}-\text{r},\text{t}$
$\text{d}-\text{q},\text{t}$
$\left(a\right)3Cu+\underset{\left(dil\right)}{8HN{O}_3}\to 3Cu(N{O}_3{)}_2+2NO+4H_{2}O$

$\left(b\right)3Cu+\underset{\left(conc\right)}{4HN{O}_3}\to Cu(N{O}_3{)}_2+2N{O}_2+2H_{2}O$

$\left(c\right)4Zn+\underset{\left(dil\right)}{10HN{O}_3}\to 4Zn(N{O}_3{)}_2+N_{2}O+5H_{2}O$

$\left(d\right)Zn+\underset{\left(conc\right)}{4HN{O}_3}\to Zn(N{O}_3{)}_2+N{O}_2+2H_{2}O$
