2. 3-Methyl-2-butanone
What would the H NMR spectra look like for the compounds: 1. 3-Hydroxybenzaldehyde 2. 3-Methyl-2-butanone
Practice Problems: 1a. Analyze the given H NMR spectrum of 3-methyl-2-butanone. Explain why there are 3 different signals. Assign the signals to the correct H's. 3-methyl-2-butanone 1b. Do the observed splitting patterns follow the N+1 rule? Explain. .2 3.0 2.8 fi (ppm) 2.6 2.4 2.2 2.0 1.8 1.6 1.4 1.2 1.0 0.8 0. Be very careful: it is NOT the number of H's giving rise to a signal that determines its splitting pattern. Instead, it is the number of H's...
