CHEM 14C Study Guide - Final Guide: Alkyne, Fluorine, Hydrogen Bond
Document Summary
Chemistry 14c winter 2017 final exam part b solutions page 1. Statistics: high score, average, and low score will be posted on the course web site after exam grading is complete. Some questions have more than one answer, even though only one answer may be listed here. To see the final projected course grade cutoffs, consult the grading scale on the chemistry 14c course web page: ketone (in ibudilast) and amine (in methamphetamine). Alkane and carbonyl are not considered functional groups because they are so ubiquitous: four lone pairs. One on each nitrogen atom, and two on the oxygen atom. Other contributors are less significant, and therefore earn less credit: contributor a. This is the only contributor that does not violate any resonance contributor preference rules. Of the answer choices, ibudilast has the most conjugated p orbitals: bond b. rotation around bond b disrupts conjugation, whereas rotation around bond a or bond c does not. (a) twelve pi electrons.
