Question

Which of the following is not true for 'Borazines'?

• A. Borazine is more reactive than benzene
• B. \( \text{B}_3\text{N}_3\text{H}_6 + 3\text{HCl} \rightarrow \text{B}_3\text{N}_3\text{H}_6\text{Cl}_3 \)
• C. Borazine reacts with water to form ammonium chloride
• D. Borazine forms \( \pi \) complexes

Hint:

Borazine is more reactive than benzene and can form \( \pi \)-complexes, but it does not react with water to form ammonium chloride.

Answer 1

The Correct Option is C

Step 1: Reactivity of Borazines.
Borazines are often referred to as "inorganic benzene" because of their structural similarity to benzene. However, borazine is more reactive than benzene, especially in nucleophilic substitution reactions. Thus, option (1) is true.

Step 2: Reaction with HCl.
Borazine reacts with HCl to form a chlorinated product, as shown in option (2). This is a common reaction for borazines. Therefore, option (2) is true.

Step 3: Reaction with Water.
Borazine does not react with water to form ammonium chloride. Instead, it undergoes hydrolysis to form boric acid and ammonia, not ammonium chloride. Thus, option (3) is false and is the correct answer to this question.

Step 4: Formation of \( \pi \)-Complexes.
Borazine can form \( \pi \)-complexes due to the similarity to benzene in its electronic structure. Hence, option (4) is true.

Step 5: Conclusion.
The correct answer is (3) Borazine reacts with water to form ammonium chloride, as this statement is not true.
