The presence of a lone pair decreases the bond angle between the bonding pair of electrons, due to their high electric charge which causes great repulsion between the electrons. They are also used in the formation of a dative bond.
â¢ When determining the electron pair geometry, lone pairs and bonds are considered and when determining molecular geometry only bonded atoms are considered. â¢ If there arenât any lone pairs around the central atom, the molecular geometry is as same as the electron pair geometry.
