Which of the following statements is TRUE?
A) Ammonia has trigonal planar electron geometry and tetrahedral molecular geometry.
B) Ammonia has tetrahedral electron geometry and trigonal pyramidal molecular geometry.
C) Ammonia has trigonal pyramidal electron geometry and tetrahedral molecular geometry.
D) Ammonia has trigonal planar electron geometry and trigonal bipyramidal molecular geometry.

Question

Quizplus · Accepted Answer

The electron geometry of ammonia is tetrahedral because it has four electron pairs around the central nitrogen atom. However, one of these electron pairs is a lone pair, which takes up more space than the bonding pairs. This causes the molecular geometry to be trigonal pyramidal, with the three hydrogen atoms at the corners of a triangle and the lone pair at the apex. Therefore, option B is the correct statement.
