Chemical Bonding Exam: Trivia Quiz! MCQ - Quiz

What can be said about chemical bonding? Chemical bonding is any interaction that accounts for molecules, ions, crystals, and other stable materials that create the familiar substances in our daily lives. Suppose the complete energy of a group of atoms is lower than the sum of the component atoms' energies. In that case, they then bond collectively, and the energy lowering is the bonding energy. This quiz will improve your understanding of chemical bonding. Good luck.

9.

The melting point of HBr is higher than that of HCl. Why is this so? Both substances exist as _________. The molecules of HBr are bigger than Hcl, therefore there is more distortion of the electron cloud and more energy is required to overcome the weak Van der Waals forces between the HBr molecules than to overcome the weaker Van der Waals forces between HCl molecules. Thus, the MP of HBr is higher than HCl.
