a) M₂C. Step 4: c) 1H-NMR analysis of product A C D The hydrolysis of an emide involves the cleavage of the amide bond, which is a carbonyl group (C=0) bonded to a nitrogen atom. This reaction is typically catalyzed by an acid or a base. E Step 3: b)IR analysis of product A: The broad peaks in the range of 3500 cm³ to 2500cm* indicate O-H stretching frequency of COOH functional group... The strong, narrow peak around 1720 cm* indicates C=0 stretching frequency of COOH. The medium, sharp peak around 1600cm* indicates C-C stretching frequency of benzene ring Proton A: The small, broad peak around 12 ppm indicates O-H of COOH. Proton B and proton C: The doublets at 8.1ppm, 7.1ppm indicate di-substituted benzene. Proton D: The quartet at 2.4 ppm indicate CH₂ unit with adjacent CH₂ unit. Proton E: Triplet et 1.1 ppm indicate CH₂ unit with adjacent CH₂ unit.

What are the errors in the following answer?

In the presence of excess base and excess halogen, a methyl ketone is converted to a carboxylate ion. The reaction is known as the haloform reaction because one of the products is haloform (chloroform, bromoform, or iodoform). Before spectroscopy became a routine analytical tool, the haloform reaction served as a test for methyl ketones: the formation of iodoform, a bright yellow compound, signaled that a methyl ketone was present. Why do only methyl ketones form a haloform?
