Starkey Created Date: 4/10/2014 10:24:48 PM You will find a short table of useful chemical shifts at the end of the questions. by lbellop. A Quiz On Proton NMR: Trivia! Interpretation of spectra is a technique that requires practice - this site provides 1 H NMR and 13 C NMR, DEPT, COSY and IR spectra of various compounds for students to interpret. Which molecule will produce the following spectra with 3 different H environment? Most NMR questions on an exam involve determining a specific structure rather than memorizing and repeating various NMR values. Challenge Yourself!!! Typically, you will be given an NMR spectra and a molecular formula (sometimes an IR spectra will be provided). Answer: c. 12. Question 1 ... (CH 3) 3 CCH 2 CHO have in 1 H NMR and 13 C NMR spectra? This session helps to analyze students learning achievements. For each example you should find the number of signals you expect, where they should show on the scale (chemical shift), and what shape they should be (splitting patterns). 50% average accuracy. 11.
