Hi I included the polarity ranking in the post. It has a region of partial charge. In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole moment, with a negatively charged end and a positively charged end.. Polar molecules must contain polar bonds due to a difference in electronegativity between the bonded atoms. Amino acids differ from each other with respect to their side chains, which are referred to as R groups. Pretty sure I learned Aoxygen is more electronegative than nitrogen, so the O-H bond is more polarized than the N-H bond and therefore hydrogen bonding is stronger. Update: this is the polarity ranking: COOH > Amide > OH > Amine > Aldehyde and ketone > ester > ether > alkane.

The grafting of an olefinic monomer like acrylonitrile (AN), methyl methacrylate (MMA), and styrene (ST) onto natural rubber (NR) was carried out to enhance the polarity of the new chemical groups on the NR backbone and, in turn, to improve the filler-rubber interaction. I understand aldehyde is more polar than ester due to the H-bonding, but why is ketone more polar than ester, when ester has 2 oxygens than ketone's? If not, why not? Which is more polar hydroxyl group or carbonyl group? As , EL NORTE is a melodrama divided into three acts. I saw somewhere on here that the amide group is more polar due to its ability to hydrogen bond more because its group would be NH2 versus the OH on the carbonyl group so according to that B would be the right answer. One of the question explanations gave the polarity ranking as: carboxylic acid > amide > alcohol > amine > aldehyde/ketone > ester > ether > alkane However, Solution : In the carbonyl group `(gtC = O)` the `pi`-electron pair is loosely held and can be readily shifted to the oxygen atom. In chemistry, the definition of a polar molecule, is a molecule that has a charge on one side of the molecule, that is not cancelled out. Carboxylic Acids are the most polar functional group because they can hydrogen bond extensively, they have a dipole moment and 2 electronegative atoms. These are only some of the basis chemical properties and physical properties which can be identified through the presence of a functional group in the organic molecule chain.
