1.	What is the minimum number of reactions required for the conversion of aniline to 1,3,5-tribromobenzene?(a) 2(b) 3(c) 4(d) 5The question was asked in examination.The above asked question is from Diazonium Salts in Synthesis of Aromatic Compounds topic in portion Amines of Chemistry – Class 12
Answer» The CORRECT answer is (B) 3 To explain: The three reactions are as FOLLOWS: \(\Rightarrow\) Reaction 1: Aniline on treatment with bromine water gives 2,4,6-tribromoaniline. \(\Rightarrow\) Reaction 2: This on diazotisation with HNO2 gives 2,4,6-tribromobenzenediazonium CHLORIDE. \(\Rightarrow\) Reaction 3: This on reaction with H3PO2, reduces the diazo group to hydrogen, to give 1,3,5-tribromobenzene.
