An oxygen-containing compound which shows sharp IR absorption at 2200 cm^-1 and 3300 cm^-1 is likely to contain which functional group?

Question

Quizplus · Accepted Answer

The sharp absorption at 2200 cm-1 indicates the presence of a C≡C triple bond, which is characteristic of alkynes. The absorption at 3300 cm-1 indicates the presence of an -OH or -NH functional group, but neither of these is present in the options. Therefore, the only option that contains an alkyne functional group is choice C.
