Boiling point increases down the group, because of increasing strength of van der Waals (intermolecular) forces. More energy is required to break van der Waals (intermolecular) forces.Follow up questions ...
It is really important to note here that there are no intermolecular force of attraction between the molecules, compared to simple covalent molecules. There are only strong covalent bonds which means that...
The forward and backwards reaction have the same rate so there is no overall change in the quantity of reactants and products.
A H-bond is an attraction between molecules. It is therefore an intermolecular force, and in fact one of the strongest. Molecules which exhibit H-bonding must contain a hydrogen that is directly bo...
