What is the hybridization of sulfur in $SO_2$?

Write the state of hybridisation of carbon in the following compounds and the shapes of each of the molecules:
$(a)$ $H_2C=O$
$(b)$ $CH_3F$
$(c)$ $HC \equiv N$

Match the shapes of the compounds given in List-$I$ with the types of hybridization given in List-$II$.

List-$I$	List-$II$
$(1)$ Tetrahedral	$(A)$ $sp^2$
$(2)$ Trigonal planar	$(B)$ $sp$
$(3)$ Linear	$(C)$ $sp^3$

Determine the hybridization of the sulfur atom in the $SO_3$ molecule.

How many of the following species have $sp^3$ hybridisation of the central atom?
$SO_3$ (Solid),$H_3PO_2$,$S_2O_3^{2-}$,$XeO_2F_2$,$I_3^-$,$N_2O$,$NH_2^-$

Which of the following sets of species have the same hybridisation state but different shapes?
