Inorganic benzene is

• A

  $\mathrm{B}_3 \mathrm{~N}_6 \mathrm{H}_3$
• Correct answer
  B

  $\mathrm{B}_3 \mathrm{~N}_3 \mathrm{H}_6$
• C

  $\mathrm{Al}_3 \mathrm{~N}_3 \mathrm{H}_6$
• D

  None of these

Solution

$\mathrm{B}_3 \mathrm{~N}_3 \mathrm{H}_6$ (borazine) is known as inorganic benzene. Borazine is isoelectronic (ie, same number of electrons) and isosteric (ie, same number of atoms) with benzene.

Hence, the correct answer is option: 'B'.
