Q63 / 160 · JIPMER 2006 · Chemistry

With which of the given pairs $\mathrm{CO}_2$ resembles?

  • Correct answer
    A
    $\mathrm{HgCl}_2, \mathrm{C}_2 \mathrm{H}_2$
  • B
    $\mathrm{HgCl}_2, \mathrm{SnCl}_4$
  • C
    $\mathrm{C}_2 \mathrm{H}_2, \mathrm{NO}_2$
  • D
    $\mathrm{N}_2 \mathrm{O}$ and $\mathrm{NO}_2$

Solution

$\mathrm{CO}_2, \mathrm{HgCl}_2$ and $\mathrm{C}_2 \mathrm{H}_2$ all are linear in shape. $\mathrm{O}=\mathrm{C}=\mathrm{O}, \mathrm{Cl}-\mathrm{Hg}-\mathrm{Cl}, \mathrm{HC} \equiv \mathrm{CH}$.

Hence, the correct answer is option: 'A'.
