What are Phosphonitrilic halides?
What are Phosphonitrilic halides?
Answer:Phosphonitrilic halides are compounds of form X2P=N, or polymers thereof, where X is a halogen.
What are the Phosphonitrilic compounds?
Phosphonitrilic chloride tri~ner, tetramer, and polymer have been studied by X-ray and electron diffraction (23-28). The trimer exists as an almost planar six- membered ring, the tetramer as a puckered eight-membered ring, and the polymer as a linear chain which is arranged in the form of a helix.

What is basic unit of Polyphosphazene?
1.16. Polyphosphazenes (PPHOSs) are polymers with an inorganic backbone consisting of alternating phosphorus and nitrogen atoms, separated by alternating single and double bonds, and organic substituents (R) covalently bonded to the phosphorus atoms as side groups (see Scheme 1.44).
What is Phosphonitrilic chloride?
a polymer composed mainly of hexachlorocyclotriphosphazotriene. Freshly produced phosphonitrilic chloride is an amorphous substance that partially crystallizes upon extension. Density, 2.4 g/cm3 at 20°C.
What is the other name of Borazine?
Borazine, also known as borazole, is a polar inorganic compound with the chemical formula B3H6N3. The compound is isoelectronic and isostructural with benzene. For this reason borazine is sometimes referred to as “inorganic benzene”.
What is Polyphosphazene used for?
Polyphosphazenes are polymers containing nitrogen as part of their backbone; they are commonly used in O-rings, pipelines, and seals in oil, fuel delivery, and storage systems.
What are uses of Phosphazenes?
Phosphazenes are also used as surface coatings and composite materials. Derivatives have been synthesized to be inert in biological media and are known to function well subcutaneously. High Performance: Polyphosphazenes are used as flame retardants, additives, performance polymers, and in specialty applications.
What is inorganic rubber?
into an amorphous substance which is insoluble and infusible, and whose mechanical properties are similar to those of rubber. It is, for this reason, generally known as inorganic rubber.
What is the name of pncl2 4?
Poly(dichlorophosphazene), also called dichlorophosphazine polymer or phosphonitrilechloride polymer, is a chemical compound with formula (PNCl2)n….Poly(dichlorophosphazene)

| Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). |
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.
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.
Which is the only well defined series of phosphonitrilic halides?
The only well-defined series, which have been studied, are the siloxanes (R2SiO), and the phosphonitrilic chlorides (PNC12) based respectively on the isoelectronic repeating units SiO and PN. They each form extensive series of both cyclic and related linear polymers.
What is the oxidation state of phosphazenes halides?
PHOSPHAZENES OR PHOSPHONITRILIC HALIDES Nitrogen and phosphorus catenate together, forming an interesting series of polymers containing P-N single bonds and P=N double bonds. In these compounds, the phosphorus atom is in a +5 oxidation state, and the nitrogen atom is in a +3 oxidation state. The compounds are formally unsaturated.
When does the action of phosphonitrilic derivatives 349 subside?
The initially vigorous re- PHOSPHONITRILIC DERIVATIVES 349 action slowly subsides, until after 6-8 hr the evolution of hydrogen chloride is barely noticeable. The excess of ammonium chloride is filtered off, and the solution concentrated under reduced pressure a t as low a temperature as possible.
What are the different uses of phosphorus halides?
Ans: The various uses of Phosphorus Halides are as follows: We use phosphorus halides as a chlorinating agent. Specifically, it is used in cleaning water bodies. Also, we utilise them for making water treatment agents. Too often, we use them to make organophosphorus pesticides.
