Be sure to answer all parts. For the following compound give the number of H NMR signals, and then determine how many peaks are present for each NMR signal Part 1 Number of signal(s): 2 Part 2 out of 2 Ha o CH H peak(s) H peak(s) Check my work Next part attempts left

Answer 1

The number of 'H NMR signals is evaluated from the given structure as shown below CH3-C-H На нь Since, the number of signals is equal to the number of different type of H atoms in given compound and marked as Ha and H Hence, the number of H NMR signals is2 Four peak is observed for H, Since this proton was coupled with three hydrogen of methyl group and gives quartet in the NMR spectrum Two peak is observed for Hg Since these three protons were coupled with one hydrogen of aldehyde group and gives doublet in the NMR spectrum
