Identify the compound from the given infrared spectrum.
Understand the Problem
The question is asking to identify a chemical compound based on the provided infrared spectrum. The graph shows absorbance at various wavelengths, which can indicate specific functional groups present in a compound.
Answer
A. butanol
The final answer is A. butanol
Answer for screen readers
The final answer is A. butanol
More Information
The broad peak around 3400 cm⁻¹ indicates an O-H stretch typical of alcohols. Additionally, the absence of a sharp peak near 2100 cm⁻¹ rules out alkynes (like 2-methyl pentyne), and butanol has similar peaks.
Tips
A common mistake is ignoring the broadness of peaks which signifies the presence of hydrogen bonding in alcohols.
