What is VSEPR Theory?

Back

VSEPR Theory (Valence Shell Electron Pair Repulsion Theory) is a model used to predict the geometry of individual molecules based on the repulsion between the electron pairs in the valence shell of the central atom.

What is the bond angle in a trigonal planar molecular shape?

Back

120 Degrees.

Front

What is the effect of lone pairs on bond angles in a molecule?

Back

Lone pairs repel more strongly than bonded pairs, which can reduce the bond angles between bonded pairs.
