WebbMolecule Shapes The shape of a molecule can be determined by considering the type and quantity of electron pairs : 1. Find the number of electron pairs. 2. Determine how many of the pairs are bonding pairs and how many are lone pairs. 3. Bonding pairs indicate the basic shape and lone pairs indicate any additional repulsion.

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. WebbSo based on the total number of electron pairs, there are a few distinct basic shapes and bond angles that we need memorise. 2 electron pairs - linear 3 electron pairs - trigonal planar 4 electron pairs - tetrahedral 5 electron pairs - trigonal bipyramidal 6 electron pairs - octahedral 2.
