In the water molecule, the oxygen and hydrogen atoms share electrons in covalent bonds. There are a total of ... Alcohol has one O–H bond which is polar, but a large portion of the molecule is made up ...

A substance that contains polar covalent bonds may not be overall polar. This is due to the shape of the molecule. Water molecules are polar molecules. Both of the bonds inside the molecule are ...

so the formula of water is H 2 O. A nitrogen molecule is made up of two nitrogen atoms joined together. Nitrogen atoms can form three covalent bonds, so a triple bond forms between them.

The sucrose molecules dissolve as they are separated from the other molecules and mix into the water. The sucrose molecule has many oxygen-hydrogen (O–H) bonds which are polar. The charge-density ...
