Explicación
1. A molecule with a trigonal-planar shape has no lone pairs. This is because the three atoms surrounding the central atom are evenly distributed around the central atom, forming a flat, triangular shape.2. A molecule with a bent shape and a trigonal-planar electron domain shape has one lone pair. The presence of the lone pair causes the molecule to have a bent shape, while the electron domain shape remains trigonal-planar.3. A molecule with a trigonal-pyramidal shape has one atom and one lone pair around the central atom. The lone pair causes the molecule to have a pyramidal shape, with the three atoms forming the base of the pyramid and the lone pair forming the apex.
