    IIT JEE Examination is held at two levels: JEE Main and JEE Advanced. IIT JEE Advanced 2017 Examination is the only way to get into prestigious IITs.

    About Practice Paper

    This JEE Advanced Solved Chemistry Paper-1 in this article consists of 18 questions divided into three sections. The questions in this paper have been asked from the complete syllabus.  Each question of this paper is very important from examination point of view and has been developed very carefully by Subject Experts at Jagranjosh.

    The format and the marking pattern of the paper is as below:


    Question Type

    Number of Questions

    Full Marks

    Partial marks

    Negative Marks

    Sectional Maximum Marks


    Single correct option


    If only the bubble corresponding to the correct option is darkened


    In all other cases



    One or more correct option(s)


    if only the bubble(s) corresponding to all the correct option(s) is or are darkened

    For darkening a bubble corresponding to each correct option, provided NO correct option is darkened

    In all other cases



    Single digit integer (0-9)


    If only the bubble corresponding to the correct answer is darkened




    Few questions from the practice paper are given below:

    Q.     According to kinetic theory of gases collisions are always elastic

    (a)   heavier molecules transfer more momentum to the wall of the container

    (b)  only a small number of molecules have very high velocity

    (c)   between collisions, the molecules move in straight lines with constant velocities

    (d)  between collisions, the molecules move in straight lines with constant velocities


    Correct Option: (a)

    According to a postulate of kinetic theory of gases, collision between the    molecules as well as with the wall of container is perfectly elastic in nature.

    Hence, option (a) is correct

    All other statements are incorrect.

    Q.    Benzene and naphthalene form an ideal solution at room temperature. For this process, the true statement(s) is (are)

    (a)  ΔG is positive                      

    (b)  ΔS system is positive

    (c)  ΔS surroundings = 0

    (d) ΔH =

    Correct Option(s): (b), (c), (d)


    When an ideal solution is formed process is spontaneous

    According to Raoult's law, for an ideal solution

    ΔH = 0, ΔVmin = 0

    From the relation

    ΔG = ΔH ΔS

    Since, ΔH =

    ΔG = – ve

    and ΔS surroundings = 0

    Therefore, ΔS sys. = + ve

    Q. In the titration of HClversus NaOH, the pH of the solution at equivalence point (when temperature is 25C) is

    Correct Answer: 7


    At the equivalence point, the solution will contain NaCl. Its pH would be 7.
