I've zoomed in and taken more pictures of the 4 H NMR spectrum. I would appreciate any explaination or work. Thank you so much!!
Homework Answers
SOLN 6
The structure is Isobutylbenzene
The signal 'A' is due to 6H of two Methyls that appears at upfield around 1 ppm. it split into double to 1 neighboring CH protons
The signal 'B' 1 H septet is due to CH protons adjacent to two CH3 groups
then signal 'C' is due to 2H of CH2 adjacent to CH hence give doublet at 3 ppm
the final sinal at 7-8 ppm is due to aromatic protons which gives multiplet due to complex splitting
