Practice: Predict the splitting pattern (multiplicity) for the following molecule: 

Practice: Predict the splitting pattern (multiplicity) for the following molecule:

Practice: Which of the following compounds gives a 1H NMR spectrum consisting of only a singlet, a triplet, and a pentet? 

Additional Problems
Draw schematically the signals that will appear in the  1H NMR spectrum for the protons labeled with an asterisk. 
What is the splitting of each of the protons on the following molecule? a. _____________________________________ b. _____________________________________ c. _____________________________________ d. _____________________________________ e. _____________________________________ f.  _____________________________________ g. _____________________________________ h. _____________________________________
Which of these compounds will show two triplets (among other signals) in their   1H NMR spectra? A) I, II, III B) I only C) I, III only D) II only
Indicate the splitting patterns expected for all of the equivalent sets of hydrogens in the molecule below. Assume that you observe the maximum possible number of peaks in each resonance. Also, assume that the splitting is negligible beyond 3 bonds.
Sketch the  1H NMR spectrum of methyl propionate. Match the peaks with the protons in the structure. Mark the splitting patterns (e.g. singlet, doublet, triplet, or quartet) and number of protons for each signal (e.g. 1H, 2H, or 3H).
Predict the spiltting pattern for the structure below in order of protons a, b, c:a. doublet, doublet, singlet b. doublet, triplet, triplet c. triplet, triplet, triplet d. triplet, triplet, singlet e. doublet, doublet, doublet
Splitting: For each structure below, indicate the splitting for each signal. Use these abbreviations for the splitting : s=singlet; d=doublet; t=triplet; q=quartet; etc. If there is complex splitting, indicate the total # of peaks and how the splitting is produced. e.g. d of t
