Document Summary

Chem 14c lecture 1 spring 2016 exam 2 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 projected course grade cutoffs, consult the grading scale on the chemistry 14c course web page. X-ray crystallography depends on photon diffraction, not photon absorption. (a) molecule a (sucrose) and molecule b (lactose). A quick check of the formulas answers the question, and calculation verifies if necessary. (b) molecule a (sucrose) and molecule b (lactose). These have the most carbons; carbon is the greatest contributor to m+1. For m+1 intensities, four nitrogen atoms ~ one carbon atom. No calculations are needed. (c) molecule a (sucrose) and molecule b (lactose). Molecular ion portion of the mass spectrum (m, m+1, and.
