MCQ
Mark the incorrect statement from the following.
  • A
    Benzene has a planar structure.
  • B
    Benzene is an unsaturated hydrocarbon and shows addition reactions like alkenes.
  • C
    In benzene carbon uses two p-orbitals for hybridisation.
  • D
    Aromatic hydrocarbons contain high percentage of carbon hence burn with sooty flame.

Answer

  1. Benzene is an unsaturated hydrocarbon and shows addition reactions like alkenes.

Explanation:

The statement given in the second option is incorrect.

Benzene can show both additions as well substitution reaction. It does not show an addition reaction like alkene.

This is because, if it shows an addition reaction like alkene, then it will lose its aromaticity and become less stable.
