Which of the following molecules has no lone pair of electrons on central atom?

Which of the following molecules has no lone pair of electrons on central atom?
  1. $\mathrm{SO}_2$
  2. $\mathrm{SF}_6$
  3. $\mathrm{NH}_3$
  4. $\mathrm{SF}_4$

Solution

$\begin{array}{|c|c|} \hline \text{Molecule} & \begin{array}{c} \text{No. of lone pairs on the} \\ \text{central atom} \end{array} \\ \hline \mathrm{SO}_2 & 1 \\ \hline \mathrm{SF}_6 & 0 \\ \hline \mathrm{NH}_3 & 1 \\ \hline \mathrm{SF}_4 & 1 \\ \hline \end{array}$
