Using VSEPR theory, predict the electron group geometry, molecular shape, and the bond angles in a molecule that contains 4 electron groups 3 bonds and 1 lone pair electrons).

Question

Quizplus · Accepted Answer

The electron group geometry is tetrahedral because there are 4 electron groups around the central atom. The molecular shape is trigonal pyramidal due to the presence of 3 bonding groups and 1 lone pair. The bond angles are slightly less than 109.5° because the lone pair repels the bonding pairs more strongly, causing them to move closer together.
