Then, going from Br to Cl, CH 3 is turning to the right, giving you a R. Neither R or S: This molecule is achiral. You have to switch the H and Br in order to place the H, the lowest priority, in the back. As the highest priority functional group, esters get the suffix -oate. Functional groups are arranged in order of priority. On the order of acidity: Carboxylic Acid and Acid Anhydride > Phenol > Alcohol >>> Amine The above order lies rather neatly, for the carboxyl group is acidic, while the amine group is basic so alcohol must be in the middle. Double and triple bonds are also functional groups. Now that the functional groups and substituents from Groups A, B, and C have been described, a modified set of steps for naming organic compounds can be applied to all simple structures: •Step 1. Find the highest priority functional group. Even if other parts of the molecule are quite different, certain functional groups tend to react … The highest-precedence group takes the suffix, with all others taking the prefix form. Answered By This is due to the idea that the alcohol functional group contributes more to the unique geometry and likelihood of specific reactions than the triple and double bonds do. Find the highest priority group. Close . Also available in Class 11 Medical - Nomenclature of Organic Compounds Class 11 Engineering - Nomenclature of Organic Compounds Class 10 - Nomenclature of carbon compounds.
