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:

Answer»

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