  • B
    The C−X bond in haloalkanes is less polar than the C−X in haloarenes.
  • C
    Polarity of C−X bond in haloalkane is equal to the polarity of C−X bond in haloarenes.
  • D
    Polarity of C−X bond in both depends on conditions.

Answer

  1. The C−X bond in haloalkanes is more polar than the C−X in haloarenes.

Explanation:

In haloarenes due to resonance, charge distribution or rotation of charge on benzene nucleus takes place hence the C−X bond in haloalkanes ( which are not aromatic) is more polar than the C−X bond in halo arenes (aromatic).
