Questions: Part C Ionic compounds are formed from ionic bonds, whereby an electron is transferred from the metal cation to the nonmetal anion. Ions form solid lattices of ions. Covalent compounds form solids through the attraction of two covalent molecules. Since the attraction between two covalent molecules is weak compared to the ionic bonds holding an ionic compound together, ionic compounds tend to have higher melting points. Which of the following compounds has the highest boiling point? Br2 NaBr HBr BrF

Solution Steps

Step 1: Identify the Type of Compounds
  • Determine whether each compound is ionic or covalent.
  • \(\text{NaBr}\) is an ionic compound, as it consists of a metal (Na) and a nonmetal (Br).
  • \(\text{Br}_2\), \(\text{HBr}\), and \(\text{BrF}\) are covalent compounds, as they consist of nonmetals.
Step 2: Compare Bond Strengths
  • Ionic compounds generally have stronger bonds due to the electrostatic attraction between ions.
  • Covalent compounds have weaker intermolecular forces compared to ionic bonds.
Step 3: Determine Boiling Points
  • Ionic compounds typically have higher boiling points than covalent compounds due to stronger ionic bonds.
  • \(\text{NaBr}\), being ionic, is expected to have a higher boiling point than the covalent compounds \(\text{Br}_2\), \(\text{HBr}\), and \(\text{BrF}\).

Final Answer

The correct answer is NaBr.
