For the following reaction, which of the following change(s) in the IR spectrum is consistent with conversion of the reactant to the product?

Question

Quizplus · Accepted Answer

The reaction likely involves the loss of a carbon-carbon triple bond, which absorbs around 2250 cm^-1. Therefore, absorption at 2250 cm^-1 should disappear upon the conversion of reactant to product. Additionally, the formation of a new carbon-carbon double bond may result in absorptions at around 1720 cm^-1. Finally, the reaction likely involves the addition of a new functional group, which may result in absorptions in the CH or NH ranges, which are typically around 2600-2800 cm^-1. Therefore, only C includes all of the necessary changes to the IR spectrum upon the conversion of reactant to product.
