Compiled by Prof. Andri Smith, Quinnipiac College VSEPR Summary The guiding principles of VSEPR (Valence Shell Electron Pair Repulsion) Theory are that (1) electrons repel each other (because they all have like—that is, negative—charge), and (2) the energy of electrons in the valence shell (specifically, electron pairs in bonds, as well as nonbonded electron pairs) is minimized when electron pairs are as far apart from each other as possible. # of electron domains (# of effective pairs) # of lone pairs molecular formula (AX m E n ) shape 2 0 AX 2 linear 3 0 AX 3 trigonal planar 3 1 AX 2 E bent 4 0 AX 4 tetrahedral 4 1 AX 3 E trigonal pyramidal 4 2 AX 2 E 2 bent 5 0 AX 5 trigonal bipyramidal 5 1 AX 4 E seesaw 5 2 AX 3 E 2 T-shaped 5 3 AX 2 E 3 linear 6 0 AX 6 octahedral 6 1 AX 5 E square pyramidal 6 2 AX 4 E 2 square planar Some Useful Info from Loren G.
