Ammonia (NH 3) and hydrogen fluoride (HF) both also have higher boiling points than might be predicted due to presence of hydrogen bonding between the molecules.

Sucrose has many O–H bonds which are polar. These polar areas are shown with a + near the hydrogen atom and a − near the oxygen atom. The second space-filling model shows two sucrose molecules held ...

the water molecules stay together keeping the shape of the balloon. In the water molecule, the oxygen and hydrogen atoms share electrons in covalent bonds. There are a total of 10 protons and 10 ...
