Among \(\mathrm{SO}_2, \mathrm{NF}_3, \mathrm{NH}_3, \mathrm{XeF}_2, \mathrm{ClF}_3\) and \(\mathrm{SF}_4\), the hybridization of the molecule with non-zero dipole moment and highest number of lone-pairs of electrons on the central atom is
  1. \(\mathrm{sp}^3\)
  2. \(\mathrm{dsp}^2\)
  3. \(\mathrm{sp}^3 \mathrm{~d}^2\)
  4. \(\mathrm{sp}^3 \mathrm{~d}\)
