20.42 Compound B, an isomer of (Problem 20.41), is also soluble in dilute HCl. The IR<br />
spectrum of B shows no bands in the 3300-3500 cm -1 region. The broadband proton-decoupled<br />

20.43 Compound C (C9H11NO) gives a positive Tollens’ test and is soluble in dilute HCl. The IR<br />
spectrum of C shows a strong band near 1695 cm -1 but shows no bands in the 3300-3500 cm -1<br />
region. The broadband proton-decoupled 13 C NMR spectrum of C is shown in Fig. 20.9. Propose a<br />
structure <strong>for</strong> C.<br />
