The correct pairing of substances with their type of bonding is:
; polar covalentExplanation:1. (Sodium bromide) is an ionic compound, not a nonpolar covalent compound. Ionic bonding occurs between metals and non-metals, where electrons are transferred from the metal (Na) to the non-metal (Br).2. HCl (Hydrochloric acid) is a polar covalent compound. In HCl, the chlorine atom is more electronegative than the hydrogen atom, resulting in an unequal sharing of electrons and the formation of a polar covalent bond.3.
(Ammonia) is a polar covalent compound. In
, the nitrogen atom is more electronegative than the hydrogen atoms, resulting in an unequal sharing of electrons and the formation of a polar covalent bond.4.
(Bromine) is a nonpolar covalent compound. In
, the two bromine atoms have the same electronegativity, resulting in an equal sharing of electrons and the formation of a nonpolar covalent bond.Therefore, the correct pairing of substances with their type of bonding is
; polar covalent.
