A)trigonal pyramidal
B)tetrahedral
C)linear
D)bent
E)trigonal planar

Question

Quizplus · Accepted Answer

A molecule with one lone pair and three single bonds has a total of four electron domains around the central atom. This is consistent with a tetrahedral electron domain geometry. However, since there is one lone pair, one of the bonding domains is replaced by a nonbonding domain. This results in a distorted tetrahedral geometry known as a trigonal pyramidal shape.
