Unformatted text preview: below can represent a carboxylic acid. The "R" can be any organic molecule. Some functional groups are polar and others can ionize . For example, if the hydrogen ion is removed from the COOH group, the oxygen will retain both of the electrons it shared with the hydrogen and will have a negative charge. The hydrogen that is removed leaves behind its electron and is now a hydrogen ion (proton). If polar or ionizing functional groups are attached to hydrophobic molecules, the molecule may become hydrophilic due to the functional group. Some ionizing functional groups are: -COOH, -OH, -CO, and -NH 2 . Some important functional groups are shown below.
