What is the structure of borazine?
B3H6N3
Borazine/Formula
What is borazine and why it 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.
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.
Why is borazine aromatic?
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. Hence, in total it has 6 π-electrons.
What is the common name of borazine?
BH3NH3 commonly known as borazol or borazine. its IUPAC name is,Triazatriborinen. B3H6N3 is the formula.
What is the point group of borazine?
D3h point group
Borazine (A) belongs to the D3h point group.
How many bonds are there in borazine?
The given compound borazole or borazine also known as inorganic benzene has 9 single bonds and 3 double bonds.
Why is borazine more reactive than benzene?
Borazole is more reactive than benzene towards EAS reaction. Borazine is a highly polar molecule due to high Electronegativity difference between Boron and Nitrogen. The pi bonds in borazine are highly polarized than pi bonds in benzene. Thus borazine is more nucleophillic hence more reactive than benzene…
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.
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 borazine less reactive than boron?
Reason. Electrophiles attack at nitrogen and not at boron atoms in inorganic benzene.
What is the formula for the compound borazine?
Borazine is an inorganic compound with the chemical formula (BH)3(NH)3. In this cyclic compound, the three BH units and three NH units alternate. The compound is isoelectronic and isostructural with benzene.
How is the structure of the borazine ring determined?
X-ray crystallographic structural determinations show that the bond lengths within the borazine ring are all equivalent at 1.429 Å, a property shared by benzene. However, the borazine ring does not form a perfect hexagon. The bond angle is 117.1° at the boron atoms and 122.9° at the nitrogens, giving the molecule distinct symmetry.
Why is borazine an important field of Chemistry?
The chemistry of borazine and its derivatives is an important field in inorganic chemistry. It is thus natural that scientists deal with potential precursors to Si–B–C–N ceramics long before this topic became relevant for materials science. Such an example is work published by Noeth in the early 1960s [101].
What is the reaction between borazine and silazane?
The main reaction however is a dehydrocoupling of borazine–boron atoms with the nitrogen atoms of the silazanes according to Eqn (27), whereas ring-opening reactions with Si–N bond cleavage, which may also appear is less likely. Thermolysis up to 1400 °C delivers ceramics with 55–62% yield, depending on the borazine to silazane ratio used.
