In this lesson, we will learn how to identify the functional groups in a compound from the nature of the peaks in its infrared spectrum.
Q1:
A common organic chemical exhibits a strong IR absorption at 1,645 cm−1. Which of the following functional groups could have caused this absorption?
Q2:
A pure, colorless liquid with a high boiling point exhibited a strong IR absorption in the 3,300–3,400 cm−1 range. The only other strong IR signals outside of the fingerprint region can be assigned to CH resonances. To which of the following chemical families does the liquid most likely belong?
Q3:
An organic compound that is liquid at room temperature exhibits a strong IR absorption at 1,710 cm−1. It is unreactive to acidified potassium dichromate, but the product of its reaction with lithium aluminum hydride exhibits a strong IR absorption in the 3,300–3,400 cm−1 range. To which of the following chemical families does the liquid most likely belong?
