Ignoring sp³ CH stretching,estimate where the major peak be in the following compound's IR.

Question

Quizplus · Accepted Answer

The presence of sp hybridization suggests that there will be a carbonyl group (C=O) in the compound. The major peak in the IR for a carbonyl group is typically around 1700-1800 cm-1. However, since we are ignoring the sp³ CH stretching, we need to look for the next major peak. In this case, it would be the OH stretching peak, which is typically around 3300 cm-1. Therefore, the best choice is A.
