A molecule is a neutral group of atoms joined together by covalent bonds A molecular compound is a compound that composed of molecules A covalent bond is a bond formed by the sharing of electrons between atoms This is like a âtug of warâ between atoms for electrons, joining the atoms together
Description of the Carbonyl Group. It is somewhat misleading to write the carbonyl group as a covalent C=O double bond. The difference between the electronegativities of carbon and oxygen is large enough to make the C=O bond moderately polar.As a result, the carbonyl group is best described as a hybrid of the following resonance structures.hen this happens, the two valence electrons on the H-ion form a covalent bond to the carbon atom. Since carbon is tetravalent, one pair of electrons in the C=O bond is displaced onto the oxygen to form an intermediate with a negative charge on the oxygen atom.
