CHXII12:ALDEHYDES KETONES AND CARBOXYLIC ACIDS

323713 Which of the following compounds gives carbon dioxide with \(\mathrm{NaHCO}_{3}\) ?

1 Acetic acid
2 Hexanol
3 Phenol
4 Acetylene
CHXII12:ALDEHYDES KETONES AND CARBOXYLIC ACIDS

323714 Which among the following is the strongest acid?

CHXII12:ALDEHYDES KETONES AND CARBOXYLIC ACIDS

323715 Carboxylic acids, \(\mathrm{RCOOH}\), furnish \(\mathrm{H}^{+}\) ions to water forming \(\mathrm{H}_{3} \mathrm{O}^{+}\)and carboxylate ions, \({\rm{RCO}}{{\rm{O}}^{\rm{ - }}}\). The major reason for this acidic behaviour is that

1 The carboxylate ion is stabilised by solvation with \(\mathrm{H}_{2} \mathrm{O}\)
2 The carboxylic acid is stabilised by resonance
3 The carboxylic ion is stabilised by resonance
4 The carboxylic ion is more resonance stabilised than the unionised carboxylic acid
CHXII12:ALDEHYDES KETONES AND CARBOXYLIC ACIDS

323716 The correct order of increasing acidic strength is

1 Phenol \( < \) Ethanol \( < \) Chloroacetic acid \( < \) Acetic acid
2 Ethanol \( < \) Phenol \( < \) Chloroacetic acid \( < \) Acetic acid
3 Ethanol \( < \) Phenol \( < \) Acetic acid \( < \) Chloroacetic acid
4 Chloroacetic acid \( < \) Acetic acid \( < \) Phenol \( < \) Ethanol
