In the water molecule, the oxygen and hydrogen atoms share electrons in covalent bonds ... Electrons can be shared unequally in a molecule, creating a polar molecule. Opposite polar ends of molecules ...

the molecule itself is non-polar and the only intermolecular force present will be weak London dispersion forces. Ammonia (NH 3) and hydrogen fluoride (HF) both also have higher boiling points ...

The ball-and-stick and first space-filling model show that sucrose is a large molecule made up of carbon, oxygen, and hydrogen. Sucrose has many O–H bonds which are polar. These polar areas are shown ...
