Question

Which will form maximum boiling azeotrope ?

• A. $HNO_3 + H_2O$ solution
• B. $C_2H_5OH + H_2O$ solution
• C. $C_6H_6 + C_6H_5CH_3$ solution
• D. None of these

Answer 1

Answer: (A)

$HNO_3 + H_2O$ solution

Answer 2

$HNO_3 + H_2O$ solution shows negative deviation from ideal behaviour. Hence it forms azeotrope with maximum boiling point
