  1. Question 1

    Q1. During the industrial synthesis of phenol via the Dow's process, chlorobenzene is reacted with 10% NaOH. What are the required temperature and pressure?

    • A) 360C and 150 atm
    • B) 450C and 200 atm
    • C) 250C and 100 atm
    • D) 500C and 300 atm

    Answer: 360C and 150 atm

    Explanation: Dow's process requires 360C and 150 atm to convert chlorobenzene to phenol. Higher pressures like 300 atm are typical for Haber's process, not Dow's.
