Carbon Bonding and Functional Groups: Mastering Biology Answers

Carbon Bonding and Functional GroupsPart A — Carbon bondingFive displayed structures include: (1) a six-membered C/N ring with two carbonyls and one C=C bond; (2) a three-carbon alkene whose terminal carbon is drawn with only three bonds; (3) a three-carbon chain with an O substituent and terminal carbonyl; (4) a three-carbon alcohol chain; and (5) an amino-acid-like structure whose carbon between N and the carboxyl carbon has only three bonds. Select the three structures in which every carbon has the appropriate number of bonds.Part B — Identifying functional groupsA six-carbon molecule contains four functional groups. Select all atoms belonging to those groups, without selecting bonds. The reference set includes hydroxyl, carbonyl, carboxyl, amino, sulfhydryl, and phosphate structures.Part C — Classifying moleculesFor each bin—alcohol, aldehyde, carboxylic acid, amine, thiol, and organic phosphate—match one displayed molecule and the best property: polar and more water-soluble; possible structural isomer of a ketone; acts as an acid; acts as a base; forms disulfide bonds; or contributes negative charge.
