WebJun 15, 2024 · Carbonyl cations with a charge of +2 or higher tend to have weak π -acceptor interactions. Neutral carbonyls or carbonyls with a +1 or -1 charge have intermediate π -acceptor interactions. and those with a negative charge of 2- or higher have strong π -acceptor interactions. WebMay 11, 2024 · The carbonyl group is somewhat polar. That means that one end of it (the carbon atom) has a slight positive electric charge, and one end of it (the oxygen atom) has a slight negative charge. This makes the entire molecular a polar molecule. The polar nature of the carbonyl part of the molecule affects the physical properties of the entire molecule.
