An IR spectrum of an unknown organic molecule having the formula C₃H₆O reveals a strong absorption at 1230 cm^-¹ and has no absorption over 3000 cm^-¹.To what class of compounds does the unknown belong?

Question

Quizplus · Accepted Answer

The strong absorption at 1230 cm^-1 is indicative of an ether (C-O-C stretch), and the lack of absorption over 3000 cm^-1 suggests the absence of O-H or N-H bonds, which rules out alcohols and amines. Aldehydes and alkynes do not show this specific absorption pattern.
