Bonding in this molecule can be understood to involve coordinate bonding.

Which of the following reaction is not possible?

Which of the following mixtures has predominantly "Keesom forces" between the molecules?

Assertion. The atoms in a covalent molecule are said to share electrons, yet some covalent molecules are polar.

Reason. In a polar covalent molecule, the shared electrons spend more time than average near one of the atoms

Assertion. When two hydrogen atoms approach each other to form a covalent bond, nearly $435.8 \mathrm{kJ} {\mathrm{mol}}^{-1}$ of energy is released.

Reason. When two atoms approach each other to form a covalent bond between them, potential energy of the system continuously decreases.
