Can Trigonal Planar Have a Double Bond?

This molecule has regions of high electron density that consist of two single bonds and one double bond. The basic geometry is trigonal planar with 120° bond angles, but we see that the double bond causes slightly larger angles (121°), and the angle between the single bonds is slightly smaller (118°).

How many bonds does trigonal planar have?

In a trigonal planar molecule, there are 3 bonds and 0 lone pairs, with bond angles of 120∘ .

Is a double bond a trigonal planar?

Since a double bond is present and each carbon is attached to 3 atoms (2 H and 1 C), the geometry is trigonal planar. Two overlapping triangles are present since each carbon is the center of a planar triangle.
