List the signals you would expect to in an IR as evidence that there is 2,3-dibromo-3- phenylpropanoic acid present as a contaminant rather than pure 1-bromo-2- phenylethene.

Expert Solution

Pure 1-bromo-2-phenylethene will have the following Characteristics peaks in the IR spectrum -

around 3000-2800 cm^-1 and 1650 cm^-1.

But if there is any contamination of 2,3-dibormo-3-phenylpropanoic acid, then there would additional peaks at around 3600-3500 cm^-1 which will be strong and broad peak of COOH.
