Q6 / 160 · TS EAMCET 2024 (09 May Shift 2) · Chemistry

The pair of molecules/ions with same geometry but central atoms in them are in different states of hybridization is

  • Correct answer
    A
    $\mathrm{SnCl}_2, \mathrm{H}_2 \mathrm{O}$
  • B
    $\mathrm{SF}_4, \mathrm{XeF}_4$
  • C
    $\mathrm{NH}_4^{+}, \mathrm{CO}_3{ }^{2-}$
  • D
    $\mathrm{PF}_5, \mathrm{BrF}_5$

Solution

Both $\mathrm{SnCl}_2$ and $\mathrm{H}_2 \mathrm{O}$ have bent geometry. The hybridization of central atom in $\mathrm{SnCl}_2$ is $\mathrm{sp}^2$ while the hybridization of central atom in $\mathrm{H}_2 \mathrm{O}$ is $\mathrm{sp}^3$.

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