Question

Reactivity of borazole is greater than that of benzene because

• A. Borazole is non-polar compound
• B. Borazole is a polar compound
• C. Borazole is electron deficient compound
• D. Not isostructural with benzene

Answer 1

Answer: (B)

Borazole is compound because of electronegativity difference between B and N but benzene is non - polar (all C - C bonds). Hence borazole is more reactive than benzene.

Borazole (borazine) is highly polar molecular due to high electronegativity difference between boron and nitrogen. The pi bonds in borazine are highly polarised than pi bonds in benzene. It is, therefore, more nucleophilic and hence more reactive than ${\text{C}}_6{\text{H}}_6.$
