I need help interpreting this IR data for the product of a Wittig reaction.
IR data of product: 1652.17, 1462.70, 1565, 1602, 3025-Peak values in cms-1
Homework Answers
3025: sp2 C-H stretching
1652, 1602: C=C stretching aromatic
1565: C=C stretching conjugated to aromatic
1462: C-H deformation
The peak around 1652, 1565 and 1602 indicates the presence of C=C. If these were not present in your carbonyl compound as one of the starting material then it is a fair indication that reaction went to completion.
An absence of carbonyl peak around 1700-1725 is also an indication that C=C is formed as in Wittig reaction it is expected to form in place of C=O.
Please let me know any more information about the reaction you carried out (maybe reactants), then it will be easy to justify in a more concise manner.

The Wittig reaction involves coupling between a phosphonium ylide and a carbonyl-containing molecule. If a chemist wants to use the Wittig reaction to synthesize xene, which reactants should be used? Use the graded interactive module below to explore the reactivity and mechanism of the Wittig reaction and to construct the target product molecule. Click and drag a reactant molecule from each column onto the reaction stage. Note the mechanism of the reaction and the obtained products. After constructing...
