A molecule consists of four electron domain in the central atom. One of the electron domain is a lone pair. Predict the geometrical shape of the molecule.

• bent

• trigonal planar

• trigonal pyramid

• tetrahedral

Describe the principles of the valence shell electrons pair repulsion theory for predicting the shape of molecules

• Electron pair are arranged as far as possible to minimize repulsion

• Electron pair in the valence shell have same charge, repel each other

• repelling strength: BP > LP

• the molecules is spread in space to maximize bond angle

• methanal

• methoxyethane

• methanol

• propanone
