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

Answer

Brief Explanations:

A molecule with a trigonal pyramidal molecular shape has a tetrahedral electron - domain geometry because there are four electron domains (three bonding pairs and one lone pair). The presence of one lone pair causes the bond angles to be less than the ideal tetrahedral angles and gives the molecule its trigonal pyramidal shape.

Answer:

The molecule has a tetrahedral electron domain geometry with one lone pair.
