A compound,X,C₉H₁₀O,which reacts with I₂/NaOH to give a pale yellow precipitate,gives the following ¹H NMR spectrum. Singlet,$\delta$2.38 Singlet,$\delta$2.54 Multiplet (centered),$\delta$7.50 Which is a possible structure for X?

Question

Quizplus · Accepted Answer

The ¹H NMR spectrum indicates the presence of three different types of protons in the compound X, and there are no aromatic protons. This suggests that X is likely an aliphatic or saturated compound. The presence of a pale yellow precipitate upon treatment with NaOH also suggests the presence of a carbonyl group in the compound. Among the given structures, only structure III contains a carbonyl group (C=O) and has three distinct types of protons. Therefore, structure III is the best choice for X.
