The IR spectrum of a sample contains absorptions at 3050, 2950, and 1620 cm^-1. To what class of organic compound does this sample most likely belong?

Question

Quizplus · Accepted Answer

The presence of absorptions at 3050 and 2950 cm^-1 suggest the presence of C-H stretches, which are characteristic of hydrocarbons. The presence of an absorption at 1620 cm^-1 suggests the presence of a C=C double bond, which is characteristic of an alkene. Therefore, the sample most likely belongs to the class of alkenes.
