ANSWER:Solution 39P
From the 1H NMR spectrum, the 3 protons give triplet at 1.09 ppm because of this reason the three methyl group is bonded to methylene group.
The 2 protons give quartet at 2.30 ppm because of this reason the methylene group is bonded to methyl group and double bonded carbon. The enol form of propanamide has one NH proton and one OH proton. Therefore, the enol form of propanamide (
