JEE Main & Advanced Chemistry GOC Question Bank Structural and stereo isomerism

  • question_answer Rotation of plane polarised light is measured by [CPMT 1985; DCE 2001]

    A) Manometer

    B) Polari meter

    C) Viscometer

    D) Refractometer

    Correct Answer: B

    Solution :

    Polari meter is an instrument used for measuring the optical rotation. It consists of two Nicol prisms, one called the polarizer (near the light source) and the other called the analyser (near the eye). In between the polarizer and analyser, a glass tube containing the solution of an optically active compound is placed.
