Which of the following compounds gives an infrared spectrum with a peak at ~1750 cm^-¹, but no significant peaks at 3000-3500 cm^-¹ or 1050-1250 cm^-¹?

Question

Quizplus · Accepted Answer

The peak at 1750 cm-1 indicates the presence of a carbonyl group, which can be found in compound 2 (CH3COCl). The absence of significant peaks at 3000-3500 cm-1 indicates the absence of an -OH or -NH functional group, which is not present in compound 2. The absence of significant peaks at 1050-1250 cm-1 indicates the absence of a C-O or C-N functional group, which is also not present in compound 2. Therefore, compound 2 is the best choice.
