I have done part a) so you don't have to draw them. Please answer b and C. Thanks Problem #1. We have learned to recognize the multiplicity patterns: singlet (1 line), doublet (2 lines), triplet (3 lines), quartet (4), pentet (5) (or quintet), hextet (6), etc. When looking at actual 'H NMR spectra, it is important to realize that the outer lines of multiplets of peaks with N > 5 are often not visible. In other words, these lines are...

I'm not sure how to enter the data. I've tried and it looks wrong. Also C, D, E, F is what I need help with as well. I've attached a copy of my output please tell me what I am doing wrong. I would like to know how to enter the data correctly. Out put I keep getting but it looks as if it's off. what am I doing wrong? Exercise for Chapter 17 You will be analyzing the data...
thanks!! There is a mistake on this, e on compound 18a is 3 hydrogens not 2!!!! thanks again :) On each the following IR spectra, circle and indicate the most important stretching signal from the following choices:N-H, O-H, CEN, CEO, C-O, Top, IR spectrum of Compound 18a: C14H1402 Bottom, IR Spectrum of Compound 18b: C3H120. write your answer on the corresponding square provided (2.5 pts each, 5 pts total) mar 2000 6 18. Draw the structures of Compound 18a. and...
