  1. Question 1

    Q1. In the production of explosives and dyes, Picric acid is synthesized from phenol. Which nitrating mixture is required for this specific reaction?

    • A) Dilute HNO3 at room temperature
    • B) Concentrated HNO3 and Concentrated H2SO4
    • C) NaNO2 and HCl at 0-5C
    • D) Nitrogen dioxide gas

    Answer: Concentrated HNO3 and Concentrated H2SO4

    Explanation: Phenol reacts with concentrated HNO3/H2SO4 to form 2,4,6-trinitrophenol (Picric acid). Dilute HNO3 would only produce ortho and para nitrophenols.
