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 ...

The difference in electronegativity between two bonded atoms determines the bond's polarity, with a large difference indicating a polar covalent bond (e.g., H-F bond) and a small difference indicating ...

Some covalent molecular compounds have higher melting points than ... Ether is a symmetrical molecule, so even though it contains polar bonds, the molecule itself is non-polar and the only ...
