Incorrect statement about Borazine is:
- It has banana shape bonds
- It has electron delocalisation
- It reacts with water
- Cyclic in nature
The Correct Option is A
Solution and Explanation
Borazine, also known as "inorganic benzene," has the molecular formula \( \text{B}_3\text{N}_3\text{H}_6 \) and is a six-membered cyclic compound. It has the following characteristics:
- It is indeed a cyclic compound, so statement (1) is correct.
- Borazine exhibits electronic delocalization similar to benzene due to the alternating single and double bonds between boron and nitrogen, making statement (2) correct.
- Borazine can react with water to form boric acid and ammonia, so statement (3) is also correct.
- The term "banana bonds" typically refers to bonds in compounds like diborane, where boron atoms form unconventional bonds with hydrogen. Borazine does not contain banana bonds; instead, it has regular covalent bonds. Therefore, statement (4) is incorrect.
Thus, the incorrect statement is (4).

P-Block Elements
- P block elements are those in which the last electron enters any of the three p-orbitals of their respective shells. Since a p-subshell has three degenerate p-orbitals each of which can accommodate two electrons, therefore in all there are six groups of p-block elements.
- P block elements are shiny and usually a good conductor of electricity and heat as they have a tendency to lose an electron. You will find some amazing properties of elements in a P-block element like gallium. It’s a metal that can melt in the palm of your hand. Silicon is also one of the most important metalloids of the p-block group as it is an important component of glass.
P block elements consist of:
- Group 13 Elements: Boron family
- Group 14 Elements: Carbon family
- Group 15 Elements: Nitrogen family
- Group 16 Elements: Oxygen family
- Group 17 Elements: Fluorine family
- Group 18 Elements: Neon family
