Chapter 20.SE, Problem 67AP
Interpretation Introduction

a)

ORGANIC CHEMISTRY W/OWL, Chapter 20.SE, Problem 67AP , additional homework tip  1

Interpretation:

Two 1HNMR spectra belonging to crotonic acid (trans-CH3CH=CHCOOH) and methacrylic acid (H2C=C (CH3) COOH) are given. Which corresponds to which is to be explained.

1HNMR: Spectrum (a): 1.91 δ (Rel.area: 3.00), 5.83 δ (Rel.area: 1.00), 7.10 δ (Rel.area: 1.00), 12.21 δ (Rel.area: 1.00).

Concept introduction:

Crotonic acid (trans-CH3CH=CHCOOH) and methacrylic acid (H2C=C (CH3) COOH) can be easily distinguished by looking the signal for the methyl protons in these two compounds.

To explain:

Of the two 1HNMR spectra given, which belongs to crotonic acid (trans-CH3CH=CHCOOH) and methacrylic acid (H2C=C (CH3) COOH).
