Please fill out the bottom. The spectrums are on top. H H NMR. spectrum of 2-bromohexane addition product) e Markovnikov 2-bromo hexane PPM H NMR spectrum of 1-bromohexane CThe anti-Markovnikov tion product) 351 PPM B) H NMR Analysis (representative spectrum w be distributed by instructor, in which case product ratio may not agree with those from GC analysis of your own sample: attach spectrum to report and show measurements and calcs) Signals for Hydrogen Auoms Attached to Carbon Bearing the Bromine Chemical Shift (ppm) Multiplicity of Signal Height of Integration Step (mm) l-Bromo hexane: Chemical Shift (ppm) Multiplicity of Signal Height of Integration Step (mm) Product Distribution: Proportion of Product formed by lonic Mechanism Proportion of Product fromed by Free Radical Mechanism
Explanation / Answer
2-bromohexane
chemical shift: 3.60
multiplicity: multiplet (CH2-CHBr-CH3 and hence accroding n+1 rule 5+1 = 6 )
Height of the curve: Actually NMR spectrometer should give the automatic integration. Since it is absent, looking at the peak intensities 2-bromohexane is almost half of the amount to that of its counterpart)
1-bromohexane:
chemical shift: 3.51
Multiplicity: triplet ( -CH2-CH2Br, according to n+1 rule 2+1= 3)
Height: The peak intensity is almost twice to that of its counterpart)
