Predict and explain the shape and structure of an molecule:
Has _ regions of electron density
Around central _ atom
These regions repel as far as possible to minimise repulsion
Giving a bond angle of _
And a _ shape
Electron pair geometry
Two = Linear
Three = Trigonal planar
Four = Tetrahedral
Five = Trigonal bipyramidal
Six = Octahedral
Two regions of e density - 0 LP = linear (180)
3 regions of e density - 0 LP = trigonal planar (120)
3 regions of e density - 1 LP = bent (118)
4 regions of e density - 0 LP = tetrahedral (109.5)
4 regions of e density - 1 LP = Pyramidal (107)
4 regions of e density - 2 LP = Bent (104.5)
5 regions of e density - 0 LP = Trigonal bipyramidal (90 + 120)
6 regions of e density - 0 LP = Octahedral (90)
