When carbolic acid is heated with concentrated nitric acid in presence of concentrated sulphuric acid it forms
- A benzoic acid
- B picric acid
- C phthalic acid
- D benzene sulphonic acid
Answer & Solution
Correct Answer
(B) picric acid
Step-by-step Solution
Detailed explanation
When phenol is warmed with a mixture of conc. nitric acid and conc. sulphuric acid (a nitrating mixture or the mixed acid), \(2,4,6\)-trinitrophenol, commonly called picric acid, is formed.
