What is the VSEPR model, and what does it stand for
It is the valence-shell electron-pair repulsion model, predicts shapes molecules & ions via the concept that electron pairs are kept as far away from each other as possible to minimize electron pair repulsions
According to the VSEPR model, how do you treatmultiple bonds? Do multiple bonds need more space or less space than single bonds?
Each mutliple bond is treated as if it were a single electron pair. Multiple bonds require more space because of the greater number of electrons.
Tetrahedral- all 4 bonded AX4 ex. CH4
Trigonal Pyramidal AX3- 3 bonded pairs & 1 lone pair
Bent (or Angular) AX2 2 bonded pairs & 2 lone pairs
