it is bent because it has two bonding pairs and 2 lone pairs
CO32- is trigonal planar, bond angles are 1200
Formaldehyde has a nonpolar trigonal planar molecule.
Trigonal planar
Trigonal Pyramidal. It is not trigonal planar because there is one lone pair around the central atom, just like the shape of ammonia.
