As you view the graphics, the idea is to develop the concept of polarity in a visual manner. In this way, carboxyl groups are polar, and can participate in hydrogen bonding and a variety of other important reactions. Indole,2-Acetyl naphthol, and 2-methoxy benzaldehyde a library predict their reactivities specific behaviors and what are the groups. You need to ask yourself questions and then do problems to answer those questions. Look for atoms connected to other atoms with different electronegativities. Heteroatom: An atom other than carbon or hydrogen. The term polar One of the question explanations gave the polarity ranking as: carboxylic acid > amide > alcohol > amine > aldehyde/ketone > ester > ether > alkane However, Yes!

National Science Foundation > GMA > GST 236 ( 3 ):881-890. doi 10.1007/s00213-018-4985-6. Functional groups are usually classified as hydrophobic or hydrophilic depending on their charge or polarity. An example of a hydrophobic group is the non-polar methane molecule. Among the hydrophilic functional groups is the carboxyl group found in amino acids, some amino acid side chains, and the fatty acid heads that form triglycerides and As a result of carbons unique tetrahedral structure and valence number, carbon atoms can bind together in large numbers, producing carbon skeleton that can be Polar molecules occur when there is an electronegativity difference between the bonded atoms. How do functional groups relate to polarity?
