  • Question 1
    1 / -0

    Which of the following compounds has the highest boiling point?

    Solution

    Boiling point of alkyl halides increases with the increase in size and mass of halogen atom (for the same alkyl group).
    Hence, the alkyl halides in the increasing order of their boiling points are:

    R-F < R-Cl < R-Br < R-I

     

  • Question 2
    1 / -0

    Which of the following compounds has the highest density?

    Solution

    Density increases with the increase in molecular mass. Since, the atomic mass of iodine is the maximum among the halogens, hence iodopentane has the highest density among the given options.

     

  • Question 3
    1 / -0

    Which of the following has the highest boiling point?

    Solution

    Boiling point of isomeric haloalkanes decreases with the increase in branching. CH3CH2CH2CH2Br has no branching. Therefore, it has the highest boiling point.

     

  • Question 4
    1 / -0

    Which of the following compounds is an allyl bromide?

    Solution

    Allyl bromide is a compound in which bromine atom is bonded to an sp3 hybridised carbon atom next to carbon-carbon double bond (C = C).

     

  • Question 5
    1 / -0

    What are the end products of the reaction given below as per Groove's process?

    Ethanol + HCl →

    Solution

    The process leads to the removal of -OH by Cl.

     

  • Question 6
    1 / -0

    The following question has four choices, out of which ONLY ONE is correct.

    Groove's method is not used for the preparation of

    Solution

    Groove's method is not used for the preparation of C2H5F because fluorination is highly exothermic in nature.

     

  • Question 7
    1 / -0

    The formation of two chlorine radicals from a chlorine molecule is an example of

    Solution

    Homolytic fission is chemical bond dissociation of a neutral molecule, generating two free radicals, i.e. two electrons that are involved in the bond are distributed one by one to the two species.

     

  • Question 8
    1 / -0

    ...view full instructions

    Which of the following rules states that during the addition across unsymmetrical double bond, the negative part of the attacking reagent attaches itself to the carbon atom carrying lesser number of hydrogen atoms?

    Solution

    This rule explains the formation of secondary haloalkanes from unsymmetrical double bond.
