Answer:
Answer:
Methanol acts as a good solvent in ultraviolet spectroscopy but not in infrared spectroscopy. This is because of its absorbance property.
Explanation:
Methanol tends to significantly interfere with the IR spectrum as it shows strong absorbance property. This feature can ultimately result in an errored spectrum of the compound being analyzed.
In the case of UV spectroscopy, methanol does not show any absorbance and does not interfere with the spectroscopy of the dissolved compound being analyzed. This, in turn, provides us with an accurate spectroscopy result. Hence, methanol is best suited as a solvent in UV spectroscopy and not in IR spectroscopy.
