Consider the following spectrum. The compound used to generate this spectrum might have which of the following molecular formulas? A)C₇H₁₆ B)C₇H₁₆O C)C₇H₁₄ D)C₇H₁₂ E)either c or d

Question

Quizplus · Accepted Answer

Based on the spectrum, the compound contains one sulfur atom (S1), one hydrogen atom (H), and a carbon chain with 17 carbon atoms (C₇). The peak at around 1700 cm^-1 suggests the presence of a carbonyl group, which could be either a ketone or an aldehyde. The absence of a peak around 3400 cm^-1 suggests that there is no significant amount of a hydroxyl (-OH) group present. Therefore, the compound's molecular formula could be either C₇H₁₄ (with an aldehyde group) or C₇H₁₂ (with a ketone group). Therefore, the best choice would be E, either c or d.
