Describe how you could use NMR spectroscopy to distinguish between benzoyl chloride and para-chlorobenzaldehyde. The 1H NMR spectrum of para-chlorobenzaldehyde should have a signal at approximately 10 ppm corresponding to the aldehydic protone. The 1H NMR spectrum of benzoyl chloride should not have a signal near 10 ppm. The 1H NMR spectrum of benzoyl chloride should have a signal at approximately 12 ppm. The 1H NMR spectrum of para-chlorobenzaldehyde should not have a signal near 12 ppm. The 1H NMR spectrum of para-chlorobenzaldehyde should have a signal at approximately 12 ppm. The 1H NMR spectrum of benzoyl chloride should not have a signal near 12 ppm. The 1H NMR spectrum of para-chlorobenzaldehyde should have a signal at approximately 6.5-8 ppm corresponding to the aryle protone. The 1H NMR spectrum of benzoyl chloride should not have a signal near 6.5-8 ppm.
