Borazine and benzene show striking similarities in their properties. This led to a labelling of borazine as 'inorganic benzene'. However, in contrast to benzene, borazine readily undergoes addition reactions. The appropriate reason for this difference is:

Options

A. Alternate arraangement of `B` and `N` atoms in the hexagonal ring.
B. Due to the difference in electronegativity between boron and nitrogen, the cloud (electron density) is more localised on the nitrogen atoms.
C. Aromatic `phi` clouds of electron density are delocalised over all of the ring atoms.
D. Net dipole moment of borazine molecule is non-zero.

Answer

B
