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 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 aldehyde and B is a carboxylic acid.Explanation / Answer
(1) False. Nitroacetic acid is more acidic than acetic acid
(2) True, Benzoic acid is more acidic than acetic acid
(3) False.Boiling point of propanoic acid is 141.2 C while water is 100 C and 2-butanol is 98-100 C
(4) True, the range will be typically 1660-1770 .
(5) False
