Is borazine an aromatic compound?

Borazine is aromatic as there are 3 nitrogen atoms in the structure of borazine that donate two electrons each. Boron doesn’t donate any, but it has an empty p-orbital available through which the electrons can delocalize.

What is borazine and why is called inorganic benzene?

Borazine is called ‘inorganic benzene’ because the compound is isoelectronic and isostructural with benzene. The other similarities are it is a colourless liquid with aromatic smell. Borazine is said to be aromatic because the number of pi electrons obeys 4n+2 rule and the B-N bond lengths are all equal.

Which is more stable benzene or borazine?

Since inorganic benzene (borazine) contains polar coordinate bonds and organic benzene contains covalent bonds. Due to the presence of coordinate bond, borazine undergoes reaction easily and is hence kinetically less stable than organic benzene.

Is benzene aromatic or not?

Benzene is an aromatic hydrocarbon because it obeys Hückel’s rule. It is now considered aromatic because it obeys Hückel’s rule: 4n+2 = number of π electrons in the hydrocarbon, where n must be an integer. In the case of benzene, we have 3 π bonds (6 electrons), so 4n+2=6 .

Why is borazine not aromatic?

Borazine may be described as a π aromatic compound, but it is not a globally aromatic species, as the electronic system is not as delocalized as in benzene. internally strong electron delocalization (ELF = 0.823).

Is borazine planar or nonplanar?

Borazine is planar. But the borazine ring does not form a perfect hexagon. The bond angle is 117.1° at the boron atoms and 122.9° at the nitrogen atoms, giving the molecule distinct symmetry.

Is borazine known as inorganic benzene?

Borazine, also known as borazole, is a polar inorganic compound with the chemical formula B3H6N3. In this cyclic compound, the three BH units and three NH units alternate. The compound is isoelectronic and isostructural with benzene. For this reason borazine is sometimes referred to as “inorganic benzene”.

Is borazine similar to benzene?

Both borazine and benzene have similar structures with a six-membered ring, and these two compounds are isoelectronic. That means, both borazine and benzene have the same numbers of electrons or the same electronic structure.

Is borazine less reactive than benzene?

Borazine is more reactive as compared to benzene. Benzene (C6H6) which consists of C=C bonds is a non-polar molecule, whereas borazine (B3B3H6) having B-N bonds, due to electronegativity difference between B and N atoms (B is less electronegative as compared to N) is a pilar molecule (Bδ+-Nδ-).

Is Pyran aromatic?

In chemistry, pyran, or oxine, is a six-membered heterocyclic, non-aromatic ring, consisting of five carbon atoms and one oxygen atom and containing two double bonds.
