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.

Answer asap need to be answered by wednesday morning explain how a buffer works, using an ethanoic acid / sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
