Question
Indicate if the following statement is true (T) or false (F). Acetic acid is more acidic than nitroacetic acid. Benzoic acid is more acidic than acetic acid. Boiling point of propanoic acid is higher than water but lower than 2-butanol. A typical IR absorption of ketones around 1720 cm^-1 is due to C = 0 stretching vibration. Both proton NMR of compound A and B show absorption around z = 10, but A shows a broad absorption in the 3500-2500 cm^-1 and B shows two weak bands near 2720 - 2820 cm^-1. Based on this data one can safely assume that A is an adehyde and B is a carboxylic acid. The intramolecular esterification of hydroxy acids produce lactams. Both LiAIH_4 and NaBH_4 are effecient reducing agents which can be used to reduce carboxylie acids to alcohols Pyridinium dichromate (PDG) of CRO_3 are milder oxidation agents than KMnO_4 and they can be used for oxidation of secondary or tertiary alcohols to ketones. A dangerous property of ethers is easily oxidized in air to form explosive peroxides. Macrocyclic polyethers are called crown ethers. They could trap a cation such as K^+ in the molecule.Explanation / Answer
