"WebbThe Shapes of Molecules Different molecules have different shapes. The shape of a molecule is dictated by the arrangement of Electron Pairs. This is because Electron Pairs repel each other. The molecule settles in a state where the Electron Pairs are furthest apart from each other. Different types of Electron Pairs have different repulsions. " - Shapes of molecules a level
