H bonds and melting points

Postby Shreya Tamatam 3B » Thu Nov 15, 2018 10:56 pm

Why do molecules with hydrogen bonds have higher melting and boiling points?

Because hydrogen bonding is the strongest form of an intermolecular force which means it will be harder to break that bond by melting or boiling a molecule so the points will be higher

Hydrogen bonds have higher melting and boiling point because they have some of the highest intermolecular forces, so a large amount of energy is needed to separate them.

H bonds have higher melting and boiling points because the intermolecular bonds are stronger. The H bond is a very strong bond because it is highly electronegative.

In addition, hydrogen bonds are so strong because of the intermolecular forces between polar molecules. These forces are especially stronger due to the bonds between hydrogen and atoms with high electronegativity (i.e. N, O, and F).
