Mass spectrometry and infrared spectroscopy are complementary techniques because:
a. Mass spectrometry provides information about the molar mass and formula while infrared spectroscopy helps identify the functional groups in the formula.
b. Infrared spectroscopy provides information about the molar mass and formula while mass spectrometry helps identify the functional groups in the formula.
c. Mass spectrometry provides information about the carbon-hydrogen framework while infrared spectroscopy helps identify the functional groups in the framework.
d. Infrared spectroscopy provides information about the carbon-hydrogen framework while mass spectrometry helps identify the functional groups in the framework.
Question 2
Examining the infrared spectrum of a compound allows us to:
a. determine the types of functional groups present in the compound
b. determine the carbon-hydrogen framework of the compound
c. determine the molecular weight of the compound
d. determine the nature of the conjugated pi electron system in the compound
