Explanation / Answer

1. methane is sp3 hybridisation state its shape is tetrahedral.

2. CO2 is in sp hybrid state and having no lone pair . its shape is linear .

3 . CO3(2-) is in sp2 hybrid state and having no lone pair . its shape is trigonal planar .

4. SO3(2-) is in sp3 hybrid state . but three atoms are attached one lone pair is present . which also occupies the orbital and plays role in the shape of SO3(2-). its shape is trigonal pyramidal.
