How Is Trigonal Planar Made?

Trigonal planar is a molecular shape that results when there are three bonds and no lone pairs around the central atom in the molecule. The pairs are arranged along the central atom's equator, with 120° angles between them.

What makes something trigonal planar?

A trigonal planar compound has a central atom attached to three atoms arranged in a triangular shape around the central atom. All four atoms lie flat on a plane. Note that there are no lone pairs of electrons around the central atom.

What is the shape of a trigonal planar?

Trigonal planar: triangular and in one plane, with bond angles of 120°. Tetrahedral: four bonds on one central atom with bond angles of 109.5°. Trigonal bipyramidal: five atoms around the central atom; three in a plane with bond angles of 120° and two on opposite ends of the molecule.
