- The boiling point of NaBr is 1396 °C and that of HF is 19.5 °C. Which of the following answers is the best explanation for the difference in these boiling points. O NaBr is held together by ionic bonds where HF is held together by covalent bonds. O NaBr is an ionic compound and the entire solid is held together by very strong ionic bonds. This is because NaBr has far more electrons than HF and is more polarizable. O Because NaBr has a higher boiling point than HF. Submit Request Answer Part C N2 has a boiling point of -196 °C and PBr5 has a boiling point of 106 °C. Which of the following answers is the best explanation for the difference in these boiling points. This is because N2 is much smaller than PBr5 resulting in a higher boiling point. This is because PBr5 has many more electrons than N2 and, therefore, is much more polarizable resulting in a higher boiling point. This is because PBr5 is more polar than N2 resulting in a higher boiling point.
