Question

SF4 is sp3d explain

Answer 1

S atom in SF4 is bonded to four Fluorine atoms and has one lone pair (S has 6 valence electrons; four of them went in bonding with four Fluorine atoms while the other two remained as a lone pair on S atom). All of them are in hybridized orbitals. There are five such orbitals. So the hybridization is sp3d. This molecule has a see-saw shape due to the presence of one lone pair.

Note: s orbitals also participate in hybridization. One s orbital, three p orbitals and one d orbital hybridize to produce five sp3d hybrid orbits. In four of these orbitals, bond pair electrons are present. In the fifth orbital, lone pair of electrons resides.
