This document discusses molecular structures and provides Lewis dot diagrams for ammonia (NH3), oxygen difluoride (OF2), and hypochlorous acid (HOCl). It includes the Lewis dot diagrams showing the bonding between atoms in each molecule, with nitrogen in Group 5 bonded to 3 hydrogens in NH3, oxygen in Group 6 bonded to 2 fluorines in OF2, and oxygen in Group 6 bonded to chlorine and a hydrogen in HOCl.
