Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Yes, Borazine is aromatic. According to Hückel’s rules, a compound is aromatic if it satisfies three conditions: Planarity Complete delocalisation of π-electrons Presence of (4n+2)(4n+2) electrons where nn can be 1,2,3,…1,2,3,…. Borazine is aromatic as there are 3 nitrogen atoms in the structure of borazine that donate two electrons each. Boron doesn't donate any, but it has an empty p-orbital available through which the electrons can delocalize. Hence, in total it has 6 π-electrons. Though the delocalisation is lesser than that in benzene, it still is aromatic.

Borazine is made up of boron (electropositive: Lewis acid) and nitrogen (electronegative: Lewis base). ... We can see this from the resonance possibilities: one of the resonance structures has the electrons fully localized on nitrogen.
