Answers

Question 1

The double bond unsaturation of this compound is 5

The Broad peak at 12.0 ppm belongs to COOH proton.

The peaks at 7.01 ppm -7.38 ppm belongs to mono substituted phenyl ring.

The peak at 3.8 ppm belongs to CH group lies between COOH and aromatic ring.

The peak 1.8 ppm belongs to Methyl group

Using the information we can deduce the structure

Question 2

The double bond unsaturation of this compound is 0

There are two carbons .

one carbon is attached to oxygen and another methyl carbon present. Based on the molecular formula the compound must posses symmetry. it can ether group with similar groups on both side

Using the information we can deduce the structure

Question 1 COOH 2-phenylpropanoic acid Chemical Formula: CgH1002 Molecular Weight: 150.1770 ChemNMR 1H Estimation 1.46 7.35 3
