Which of the following compounds would contain characteristic IR stretches at 3300 and 2200 cm^-1?

Question

Quizplus · Accepted Answer

The characteristic IR stretches at 3300 cm-1 suggest the presence of a hydroxyl group or N-H stretch, while the stretch at 2200 cm-1 suggests the presence of a triple bond (C≡C or C≡N). Option D is the only one containing two triple bonds, hence its IR spectrum would exhibit the characteristic stretches at 3300 cm-1 and 2200 cm-1.
