  • question_answer
    Assertion : Phenol decomposes \[NaHC{{O}_{3}}\] solution to evolve \[C{{O}_{2}}\] gas.
    Reason : Picric acid is 2, 4, 6-trinitrophenol.

    A) Assertion and reason both are correct statements and reason is correct explanation for assertion.

    B) Assertion and reason both are correct statements but reason is not correct explanation for assertion.

    C) Assertion is correct statement but reason is wrong statement.

    D) Assertion is wrong statement but reason is correct statement.

    Correct Answer: D

    Solution :

    Phenol is a weaker acid than carbonic acid and hence, does not decompose\[NaHC{{O}_{3}}\] solution to evolve \[C{{O}_{2}}\] gas. Picric acid is 2, 4, 6-trinitrophenol.
