Question

T/F. When a molecule contains three bonds and a single lone pair attached to the central atom, the molecular geometry is trigonal planar.

Answer 1

False

Step-by-step explanation:

In chemistry, trigonal planar is a molecular geometry model with one atom at the center and three atoms at the corners of an equilateral triangle, called peripheral atoms, all in one plane. In an ideal trigonal planar species, all three ligands are identical and all bond angles are 120°.

Meaning there shouldn't be any lone pair.

Look up "Structure of a trigonal planar molecule" for a visual

So it is false.
