Question

Question:Borazine (B_3_N_3_H_6) has often been called “inorganic” benzene. Draw Lewis structures for borazine. Borazine is a six-membered ring of alternating boron and nitrogen atoms.

Short answer

Answer

Step-by-step solution

Definition of Lewis structure

The Lewis structure of a molecule represents the arrangement of valence electrons among the atoms in the molecule. These representations are named after G. N. Lewis. The rules for writing Lewis structures are based on the observations of thousands of molecules, which show that in most stable compounds the atoms achieve noble gas electron configurations.

Comparison of Benzene and Borazine’s reactivity:  

When compared to benzene, borazine is more reactive. Benzene (C_6_H_6) is a non-polar molecule with C=C bonds, but borazine (B_3_N_3_H_6) is a polar molecule with B-N bonds due to electronegativity differences between B and N atoms (B is less electronegative than N).

Details related to Borazine 

It is an inorganic chemical made up of boron, nitrogen, and hydrogen. Three hydroborane (BH) units and three amino units (NH) alternate in this cyclic molecule. Alfred Stock and Pohland, scientists, created the chemical in 1926 by reacting diborane with ammonia. Because the structure is isoelectronic and isostructural with benzene, borazine is referred to as inorganic benzene by Nils Wiberg, and the chemical is also known as borazol from the German term for benzene, benzol.
