In the water molecule, the oxygen and hydrogen atoms share electrons in covalent bonds ... attract and hold one molecule to another. Alcohol has one O–H bond which is polar, but a large portion of the ...

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 ...

This is due to the water expanding as it is frozen because of the hydrogen forming an open type lattice. high surface tension relatively high viscosity All ionic lattices and polar covalent ...

Hydrogen bonds are often first met in biology - Proteins, DNA where the emphasis is not on the bonding - students think that it is a full bond with a hydrogen. Students may have not met the orbital ...
