Easy MCQ +4 / -1 PYQ · JEE Mains 2023

The incorrect statement from the following for borazine is :

  1. A It can react with water.
  2. B It is a cyclic compound.
  3. C It has electronic delocalization.
  4. D It contains banana bonds. Correct answer

Solution

Borazine (B₃N₃H₆) is an inorganic compound with a structure similar to benzene, where three boron and three nitrogen atoms form a hexagonal ring, with alternating single and double bonds, and a hydrogen atom attached to each boron and nitrogen atom. <br/><br/> Option A : It can react with water. Borazine is hydrolyzed by water to form boric acid, ammonia, and hydrogen. So, this statement is correct. <br/><br/> Option B : It is a cyclic compound. Borazine has a hexagonal ring structure, making it a cyclic compound. So, this statement is correct. <br/><br/> Option C : It has electronic delocalization. The electrons in the boron-nitrogen double bonds are delocalized over the entire ring, similar to benzene. So, this statement is correct. <br/><br/> Option D : It contains banana bonds. Banana bonds are typically used to describe the unconventional, multicenter bonding in certain clusters or molecules, such as diborane (B₂H₆). Borazine does not contain banana bonds; it has a planar hexagonal structure with alternating single and double bonds between boron and nitrogen atoms. So, this statement is incorrect. <br/><br/> Thus, the incorrect statement for borazine is : It contains banana bonds.
