Yes, hydrogen bonding generally increases the melting point of substances. This is because hydrogen bonds are strong intermolecular forces that require more energy to break compared to weaker van der Waals forces. As a result, compounds with hydrogen bonding, such as water, typically have higher melting points than similar compounds without hydrogen bonding.

Hydrogen bonding in water causes molecules to be attracted to each other, requiring more energy to overcome these attractions during melting or boiling. This results in higher melting and boiling points for water compared to molecules that do not participate in hydrogen bonding.
Hydrogen bonding, which is the strongest of the intermolecular forces.
The melting point of benzoic acid is influenced by its molecular structure, which features a carboxylic acid group (-COOH) attached to a benzene ring. The presence of hydrogen bonding between the carboxylic acid groups in adjacent molecules contributes to a higher melting point, as these interactions require more energy to break. Additionally, the rigidity of the benzene ring promotes efficient packing in the solid state, further enhancing the melting point. Overall, the combination of hydrogen bonding and structural stability results in a relatively high melting point for benzoic acid compared to similar compounds.

Hydrogen bonding
hydrogen bonding increases the intermolecular attractions and therefore increases the boiling point and melting point.

Hydrogen bonding, which is the strongest of the intermolecular forces.
Hydrogen fluoride has a low melting point due to its weak intermolecular forces. The hydrogen bonding in HF molecules is relatively weak, leading to lower melting and boiling points compared to substances with stronger intermolecular forces.
Hydrogen bonding affects the properties of molecules in a chemical compound by increasing the boiling point, melting point, and solubility of the compound. This is because hydrogen bonding creates strong intermolecular forces between molecules, leading to greater cohesion and stability within the compound.
