Find the molecule-based off the IR and NMR spectrum.
Homework Answers
According mass 175 means odd no of Nitrogen atom present and 1:1 M, M+2 for one Br atom is present
NMR showed 5 different proton are present in which two showed doublet (for 3, 3 proton), one is triplet (for 2 proton) it not clearly observed and two is multiple (for 1, 1 proton)
two doublet for presence of two different -CH3. 3- methyl is upfield (1.0 to 1.5) other is (1.5 to 2.0)
H atom at C-4 is more downfield multiplet and H at C-3 is for other multiplet
In IR spectra one peak of C triplet bond N present.
m represent multiplet
d represent doublet
t represent triplet
