  • Assertion: Aryl halides are highly reactive towards nucleophilic substitution reactions. Reason : In case of haloarenes, halogen atom is attached to sp hybridised carbon atom.

    A
    If both (A) and (R) are correct and (R) is the correct explanation of (A).
    B
    If both (A) and (R) are correct, but (R) is not the correct explanation of (A).
    C
    If (A) is correct, but (R) is incorrect.
    D
    If both (A) and (R) are incorrect.

  • Aryl halides are less reactive towards nucleophilic substitutuion reaction as compared to alkyl halide due to

    A
    The formation of less stable carbonium ion
    B
    Resonance stabilization
    C
    Longer carbon-halogen bond
    D
    `sp^(3)`-hybridized carbon attached to the halogen

  • Assertion: It is difficult to replace chlorine by -OH in chlorobenzene in comparison to that in chloroethane. Reason : Chlorine-carbon (C-Cl) bond in chlorobenzene has a partial double bond character due to resonance.

    A

    Aryl halides doesn't undergo nucleophilic substitution reactions under ordinary conditions because of 1. approach nucleophilie is retarded 2. carbon carrying halogen atoms is sp^(3) - hybridised 3. the substrate molecule is destabilised due to resonance 4. partial double bond character between carbon and halogen

    Due to sp^(2) -hybridisation of C-atom holding the halogen atom, resonance effect and smaller polarity of the C-X bond, aryl halides do not undergo nucleophilic substitution reactions. Chlorobenzene can be written as a resonance hybrid of the following structures: Due to resonance, chlorobenzene gets stabilised. In chlorobenzene, the C-Cl bond acquires some double bond character and hence, it is difficult to break it as compared to C-Cl bond in alkyl halides. Similarly vinyl halides due to resonance are less reactive towards nucleophilic substitution reactions. . Which of the following is most reactive towards nucleophilic substitution reactions?

    Assertion : Carbon oxygen bond length of phenol is slightly less than that in methanol. Reason : There exist a partial double bond character and carbon to which oxygen is attached in phenol is sp^2 hybridised.
