    CBSE Class 12 Chemistry Sample Paper and Solution 2023

    Chemistry is one of the main subjects of the class 12th boards examination, it consists of a total of 100 Marks which further comprises of 70 Marks for Theory and 30 Marks for the Practical test. CBSE has recently released the official sample paper, Below are the sample question from the official paper. Practice them thoroughly so as to score good marks in chemistry, as chemistry is considered one of the scoring subjects in board exams.

    Section A 

    The following questions are multiple-choice questions with one correct answer. Each question carries 1 mark. There is no internal choice in this section.

    Question1. The major product of acid-catalyzed dehydration of 1-methyl cyclohexanol is:

    a. 1-methylcyclohexane

    b. 1-methylcyclohexene

    c. 1-cyclohexylmethanol

    d. 1-methylcyclohexane

    Solution:  b. 1-methyl cyclohexene. According to Saytzeff's rule i.e, highly substituted alkene is the major product. Here dehydration reaction takes place, an alkene is formed due to the removal of a water molecule.Question 2. Which one of the following compounds is more reactive towards SN1 reaction?

    a. CH2=CHCH2Br b. C6H5CH2Br c. C6H5CH (C6H5)Br d. C6H5CH(CH3) Br

    Solution:  c. C6H5CH (C6H5)Br

    C6H5CH (C6H5)+ carbocation formed is more stable.

    Question 3. KMnO4 is colored due to:

    a. d-d transitions

    b. charge transfer from ligand to metal

    c. unpaired electrons in d orbital of Mn

    d. charge transfer from metal to ligand

    Solution: b. charge transfer from ligand to metal The Mn atom in KMnO4 has a +7 oxidation state with electron configuration [Ar]3d 04s0 Since no unpaired electrons are present, d−d transitions are not possible. The molecule should, therefore, be colorless. Its intense purple due to L→M (ligand to metal) charge transfer 2p(L) of O to 3d(M) of Mn.Question 5. The molar conductivity of CH3COOH at infinite dilution is 390 Scm²/mol. Using the graph and given information, the molar conductivity of CH3COOK will be:

    a. 100 Scm²/mol b. 115 Scm²/mol c. 150 Scm²/ mol d. 125 Scm²/mol

    Solution:  b. 115 Scm² /mol ΛOCH3COOK = ΛO CH3COOH +ΛOKCl - ΛOHCl = 390 +150-425 = 115 Scm²/molQuestion 6. For the reaction, A +2B - AB2, the order w.r.t. reactant A is 2 and w.r.t. reactant B. What will be the change in the rate of reaction if the concentration of A is doubled and B is halved?

    a. increases four times

    b. decreases four times

    c. increases two times

    d. no change

    Solution: a. increases 4 times, Rate = [A]² If [A] is doubled then Rate’ = [2A]²= 4 [A]² = 4 RateQuestion 7. Arrange the following in the increasing order of their boiling points: A: Butanamine, B: N, N-Dimethylethanamine, C: N- Etthylethanaminaminea. Cb. Ac. Ad. BSolution: d. B
