Chem 219 Unit 5 Exam Questions With 100% Correct Answers Generic formula for alcohols - answerR-OH phenol - answerhydroxy-substituted aromatic molecules (any compound with an -OH attached to a benzene ring) IUPAC system rules for naming organic alcohols - answer- organic alcohols are named by replacing the suffix of the parent chain of the molecule with the suffix -ol - The parent chain is numbered so as to give the hydroxyl group the lowest possible number. (examples: 1-propanol, and cy...

What are the differences between aliphatic (including alkanes, alkenes,alkynes and cyclic compounds) aromatic hydrocarbons are. - ALIPHATIC Hydrocarbon: Non-aromatic -Alkanes & CycloAlkanes:single bonds; saturated:Contain only carbon and hydrogen & C-C & C-H single bonds -Alkenes:double bond(s) -Alkynes: triple bond(s) *alkenes and alkynes are unsaturated: at least one C-C double or triple bond(s) AROMATIC Hydrocarbon: benzene ring What is the trend in solubility and boiling point/mel...

BCH 462 Exam 4 Questions With 100% Correct Answers Fatty Acid Synthesis - answerFatty acids are built in several passes, processing one acetate unit at a time. The acetate is coming from activated malonate in the form of malonyl-CoA. Each pass involves reduction of a carbonyl carbon to a methylene carbon. Overall, repeating four-step sequence that elongates the fatty acyl chain by two carbons at each step, uses NADPH as the electron donor. Two enzyme-bound -SH groups serve as activating...
