Which statement describes a molecule that has a trigonal pyramidal molecular shape? the molecule has a trigonal planar electron domain geometry with one lone pair. the molecule has a tetrahedral electron domain geometry with one lone pair. the molecule has a trigonal planar electron domain geometry with two lone pairs. the molecule has a tetrahedral electron domain geometry with two lone pairs.

The correct answer is A.

Explanation:

Trigonal pyramidal is a molecular shape that results when there are three bonds and one lone pair on the central atom in the molecule. Ideally, it look as a tetrahedral geometry but in actual it is trigonal pyramidal, because according to Valence shell electrons repulsion theory, lone pair has more repulsion as compare to bond-bond repulsion, it does not remained as tetrahedral, it become trigonal pyramidal.
