Q6 / 160 · TS EAMCET 2024 (10 May Shift 2) · Chemistry

The hybridisation of central atom of $\mathrm{BF}_3, \mathrm{SnCl}_2, \mathrm{HgCl}_2$ respectively is

  • Correct answer
    A
    $s p^2, s p^2, s p$
  • B
    $s p^2, s p^2, s p^2$
  • C
    $s p^3, s p^2, s p^2$
  • D
    $s p^3, s p, s p^2$

Solution

$\begin{array}{|c|c|c|c|}\hline \text{Molecule} & \text{Hybridisation} & \text{Atomic orbital} & \text{Shape} \\ \hline \mathrm{BF}_3 & \mathrm{sp}^2 & \mathrm{~s}+\mathrm{p}(2) & \text{Trigonal planar} \\ \hline \mathrm{SnCl}_2 & \mathrm{sp}^2 & \mathrm{~s}+\mathrm{p}(2) & \text{Bent} \\ \hline \mathrm{HgCl}_2 & \mathrm{sp} & \mathrm{s}+\mathrm{p} & \text{Linear} \\ \hline\end{array}$

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