The low resolution proton spectrum of a compound contains two peaks. Which of the following compounds could not give this spectrum?
Correct answer: B. Butane
- A. Propane
- B. Butane
- C. 2-methylpropane
- D. 2,2 - dimethylpropane
Explanation
b) Butane:Butane is a four-carbon alkane with the molecular formula C4H10. In the low-resolution proton spectrum of butane, you would also expect to see two peaks. One peak would represent the three equivalent protons (CH3 group) and the other peak would represent the six equivalent protons (CH2 group) in the molecule. Therefore, butane could give a spectrum with two peaks.

About Spectroscopy and Analysis
Spectroscopy studies how substances absorb, emit or interact with electromagnetic radiation. Coverage includes ultraviolet-visible absorption, infrared identification of functional groups, Beer-Lambert law, spectral interpretation and the use of spectroscopic data to identify or determine the concentration of chemical substances.
