\(Z\) is an aromatic compound with substituents \(P\) and \(Q\). What are \(P\) and \(Q\) ?
- A \(-\mathrm{OH},-\mathrm{SO}_3 \mathrm{H}\)
- B \(-\mathrm{CHO},-\mathrm{NO}_2\)
- C \(-\mathrm{SO}_3 \mathrm{H}_1-\mathrm{NO}_2\)
- D \(-\mathrm{COOH},-\mathrm{NO}_2\)
Answer & Solution
Correct Answer
(D) \(-\mathrm{COOH},-\mathrm{NO}_2\)
Step-by-step Solution
Detailed explanation
When 2-methylhexane reacts with chromic oxide, toluene (compound \(X\) ) is formed. Further it reacts with \(\mathrm{KMnO}_4\) to form benzoic acid (compound \(Y\) ) which on reaction with nitric and sulphuric acid forms \(m\)-nitro benzoic acid (compound \(Z\) ). Therefore,…
