What NMR resonance do you predict for Maltol: splitting, shift, and area? Explain your answer. (Tables may be used)

2. Based on the NMR spectrum of the product from part B, did you obtain borneol, isoborneol, or a mixture? Explain. If you obtained a mixture of borneol and isoborneol, what was the percentage of each? Show your calculation below. Which isomer should have predominated (Isoborneol)? Why?Did your results confirm this?

Propanoic acid and methyl ethanoate are constitutional isomers. Show how to distinguish between them by IR spectroscopy. CH,CH,COH CH,COCH, Methyl ethanoate (Methyl acetate) Propanoic acid

None

3. Identify all equivalent protons and predict their approximate chemical shift. (See Table 13.3 or NMR Reference guide.) CI You CI axa CI CI CI CI

Q- savliya

a) classify the amines shown as either primary, secondary, or tertiary based on the number of carbons attached to the nitrogen atom b) what is different in the IR spectra of primary, secondary, and tertiary amines?  Is this a way to distinguish them? Explain c) explain how to differentiate amines and alcohols via IR spectral analysis

on 19 of 42 > Learning Loudon Parise SEVENTH EDITION Construct a simulated ¹H NMR spectrum, including proton integrations, for CH₂ OC(CH₂OCH (see Hint). Drag the appropriate splitting patterns to the approximate chemical shift positions; place the integration values in the small bins above the associated chemical shift. Splitting patterns and integrations may be used more than once, or not at all, as needed. Likewise, some bins might remain blank. Note that peak heights are arbitrary and do not indicate proton integrations. 30円 $ 4 R F V 7 % 5 T G B ^ 6 2H -Fo Y H MacBook Air & 7 RAM N 4 U Answer Bank J * 00 M 9H I ( 9 K ➤➤ 2 O < H ) O L 6H command P -3H sented by Macmillan Learning ^ 11 ; 0 ppm 95 { + 11 alt ? option } (1)
