Chemistry - GOC Question with Solution | TestHub

In A, bicarbonate neutralises the carboxylic acid, but released CO₂ comes from bicarbonate carbon, not the labelled ¹⁴C carboxyl carbon. The shown ¹⁴CO₂ is therefore wrong. Phenol is too weak an acid to release CO₂ from bicarbonate, making B false. Picric acid is sufficiently acidic for that reaction, so C is true. Water protonates tert-butoxide to tert-butanol and OH⁻, so D is true. Answer C,D.
