4 cards from this section. Quick, good the night before a test.
What does the Molecular Ion Peak in a mass spectrum represent?
Check what M⁺ signifies in mass spectra.
What is the primary purpose of IR spectroscopy?
Think about how molecules interact with infrared light.
What does the Base Peak in a mass spectrum represent?
Which peak stands out as the tallest in the spectrum?
True or False: Infrared spectroscopy can provide information about the molecular mass of a compound.
Think about what IR actually measures.
Given a compound with a mass spectrum showing a molecular ion peak at m/z = 58 and notable fragment ion peaks at m/z = 43, 15, and 29, determine possible structural features of the compound.
Analyze the fragments for common group patterns.
A compound has an IR spectrum showing a strong peak at 1715 cm⁻¹ and a broad peak around 3300 cm⁻¹. Propose structures that could match these spectral features.
Consider the functional groups that these peaks correspond to.
