Which substance of correctly paired with its type of bonding? NaBr; nonpolar covalent HCl; nonpolar covalent NH_(3) polar covalent Br_(2) polar covalent

The correct pairing of substances with their type of bonding is:<br /><br />$NH_{3}$; polar covalent<br /><br />Explanation:<br /><br />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).<br /><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.<br /><br />3. $NH_{3}$ (Ammonia) is a polar covalent compound. In $NH_{3}$, 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.<br /><br />4. $Br_{2}$ (Bromine) is a nonpolar covalent compound. In $Br_{2}$, the two bromine atoms have the same electronegativity, resulting in an equal sharing of electrons and the formation of a nonpolar covalent bond.<br /><br />Therefore, the correct pairing of substances with their type of bonding is $NH_{3}$; polar covalent.
