Draw dot and cross structural diagram to represent the bonding in the following simple molecular compounds. In the dot and cross diagram, show only the outer shells of the atoms involved. Molecule Dot and Cross diagram Structure Ammonia NH 3 Water H 2 O Hydrogen chloride HCl Ethane C 2 H 6 Ethene C 2 H 4 Ethanol C 2 H 5 OH Ethanoic acid CH 3 COOH

When a molecule is formed from the covalent bond, such compounds are known as covalent compounds. These compounds share one or more pairs of valence electrons. The covalent compound is a result of two non-metals reacting with each other such that they are electrically neutral. They exhibit characteristic physical properties that include lower melting points and electrical conductivity compared to ionic compounds.
