Infrared spectroscopy can be used to assess how pure a compound is. The table lists the characteristic infrared absorption frequencies of several selected bonds. Propan-2-ol is produced by the hydration of propene, and a sample of the product is collected. Which part of the infrared spectrum of the product would indicate that none of the propene is still present?
- Aabsorption in the $2900\text{ cm}^{-1}$ region
- Bstrong absorption below $1000\text{ cm}^{-1}$
- Cthe lack of absorption at or near $1250\text{ cm}^{-1}$
- Dthe lack of absorption at or near $1550\text{ cm}^{-1}$
