Cheap Grocery List For College Students, Polarity and Structure of Molecules The shape of a molecule and the polarity of its bonds determine the OVERALL POLARITY of that molecule. Acids at the top of the series- Followed by Acid derivatives- Next the poisonous batch, the cyanides-Carbonyls-Alcohols-Amines-Hydrocarbons. CARBOXYLIC ACID DERIVATIVES 3. 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. The hydroxyl group does the opposite, and would gladly give up a hydrogen to form another bond with carbon. (1) AMIDE: Perhaps it is surprising that the amide appears to be the most polar according to the data. Obviously the These functional groups, which determine the chemical reactivity of a molecule under a given set of conditions, can consist of a single atom (such as Cl) or a group of atoms (such as CO 2 H).
