Homework Answers
a) C9H10O2
a peak around 1700 cm-1 in IR implies presence of carbonyl group. A singlet around 4 ppm implies presence of O-R group. So structure is
b) C9H10O
singlet around 10.2 ppm implies presence of aldehyde group and singlets in between 2-3 ppm implies presence of aromatic-R group. As singlet around 7ppm is in shielded region so Ar-H must be in meta position with respect to aldehyde. So, structure is
c) C9H10O2
singlet around 10.5 ppm implies aldehyde group.
d)
