Step 1: Defining inorganic benzene.
Inorganic benzene is borazine, structurally analogous to benzene, with the formula B₃N₃H₆.
Step 2: Structural features.
It features a six-membered ring of alternating boron and nitrogen atoms, mirroring benzene's framework.
Step 3: Electronic delocalization.
Borazine exhibits π-electron delocalization, conferring aromatic character.
Step 4: Recognizing the correct formula.
Among the choices, only B₃N₃H₆ matches borazine.
Step 5: Conclusion.
Hence, inorganic benzene is B₃N₃H₆.
