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. WebbAmmonia. This molecule has three bonding pairs of electrons and one lone pair. Although, based on the tetrahedral shape, due to the extra repulsion from the presence of a lone pair, the 3 N-H bonds bend further away from the lone pair, in order to minimise the repulsion. The shape is described as pyramidal and has a bond angle of 107 0.

WebbIt doesn't matter about any similarity or not between the right hand side and the left hand side. The two forms are known as "cis" and "trans" isomers. They are also known as "Z" and "E" isomers. Geometric isomerism is a specific form of stereoisomerism. This form of isomerism arises because there is no rotation about the double bond.
