1 H NMR Practice Problems Dr. Peter Norris Youngstown State University The following exercises are designed to help you become familiar with predicting the 1 H NMR spectra of simple organic molecules. Question 1 . Played 8 times. Typically, you will be given an NMR spectra and a molecular formula (sometimes an IR spectra will be provided). Hopefully, these problems will provide a useful resource to better understand spectroscopy. 0. 12th grade . Title: NMR Practice Problems (Solutions) Author: Dr. Laurie S. Starkey Created Date: 4/10/2014 10:24:48 PM Protons, Neutrons, Electrons Protons, Neutrons, Electrons Atoms - Figuring Out The Number Of Protons, Neutrons, And Electrons Atoms - Figuring Out The Number Of Protons, Neutrons, And Electrons You will find a short table of useful chemical shifts at the end of the questions. I have put together a few ideas that might make this process a bit easier. Most NMR questions on an exam involve determining a specific structure rather than memorizing and repeating various NMR values. ALL THE BEST… 8 times. 1. 0. a) Integral spin b) Half integral spin c) Zero spin d) Positive spin. Your choices are: s singlet d doublet t triplet q quartet m multiplet.
