CO32- is trigonal planar, bond angles are 1200
Formaldehyde has a nonpolar trigonal planar molecule.
Bromine gas is linear because there is only two atoms involved in the molecule.
Not linear.
Sulfur tetraoxide is a trigonal planar. There is the sulfur in the middle and three oxygen that surrounds it with all of them a double bond linking them to the sulfur.
nh3
Trigonal Planar
nh3
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.
For a truly trigonal planar molecule the bond angles are 120 0 exactly.
