By the end, you can use hydrogen bonding to explain four unusual properties of water and ice.
Water molecules attract each other through hydrogen bonds. To melt ice or boil water, many of those attractions must be overcome, so water has relatively high melting and boiling points compared with similar small molecules.
The covalent O–H bonds inside each molecule are not broken when water boils. The molecules separate; they do not fall apart into hydrogen and oxygen.
