Molecular Shape deppends on the number of electron pairs in the outer orbital. The electron-pair repulsion theory relates to shape of molecules.
- electrons are negatively charged so each electron pair will repel the other pairs as much as they can
- however different types of electron pairs affect how far they repel each other
- the greatest angles are between lone pairs and this often means bonded pairs are reduced because they are pushed together by the lone pairs.
- The order of angles are:
Lone pair:Lone pair Lone pair:Bonded pair Bonded pair:bonded pair
Shapes of Molecules:
Linear Molecules:- these molecules are is a straight line and have a bond angle of…
