Compare the IRs of the reactants to the product of the baylis-hillman reaction?

Question

Compare the IRs of the reactants to the product of the baylis-hillman reaction? point out diagnostic peaks in all 3 IR spectra. please be complete in your answer. thank you.

reactant IR's:

the reactants are isonicotinaldehyde (left spectrum) and the other is methyl acrylate (right side spectrum)

if the numbers are hard to see, the left spectrum starts at 4000 and goes to 1000. the right spectrum starts at 3500 and goes to 500.

here is the basic reaction with the structures of the reactants and products to help.

Explanation / Answer

Isonicotinaldehyde

peak at 1700 - C=O stretching

2 peaks at 3350 - C-H ( aromatic C-H)

Methyl acrylate

peak at 1675 - C=O ( stretching)

1650 C=C (conjugation double bond)

3000 C-H (aliphatic C-H)

Product IR peaks

3100 - OH stretching

1700 - C=O stretching
