Which statement about VSEPR theory is not correct?
A)VSEPR is an acronym for valence-shell electron-pair repulsion.
B)In VSEPR theory, the shape or geometry of a molecule is determined by electron-electron repulsion.
C)The steric number of a central atom is the sum of the number of bonds and lone pairs around the atom.
D)The steric number has five values from 2 to 6.
E)The molecular shape or geometry always is the same as the electron-pair geometry.

Question

This statement is not always correct. In some cases, the molecular shape may differ from the electron-pair geometry due to the presence of lone pair electrons. For example, in a molecule like NH3 (ammonia), the electron-pair geometry is tetrahedral, but the molecular shape is trigonal pyramidal.
