Why anti aromatic or non aromatic systems or compounds are unstable?
Their orbitals unsymmetry make them unstable.
What is the difference between radioactive and non radioactive materials?
Radioactive substances are unstable as a result of the extra neutrons present in the nuclei of the substance. Non radioactive substances are stable.
What is a simple test to distinguish between an aliphatic compound and an aromatic compound?
Huckels rule. 4n + 2 whereby n is any integer for example 1,2,3 etc. Aromatic compounds will obey huckels rule:- (4 x (1)) + 2 = 6 (4 x (2)) + 2 = 10 (4 x (3)) + 2 = 14 Taking benzene as an example...is it aromatic? Is a six membered ring with 3 double bonds, so 6pi electrons thus obeys huckels rule and is aromatic. Negative charges also count as 2pi electrons and positive charges on a molecule are ignored entirely.
Is Biphenyl aromatic or aliphatic compound?
Biphenyl is a non planar molecule and hence should'nt be aromatic.
What elements can form compounds with argon?
Argon is an extremely stable non - raective noble gas and does not form compounds with any elements. However, in the last 10 years a compound of Argon has been reported HArF at the University of Helsinki.
Why anti aromatic or non aromatic systems or compounds are unstable?
Their orbitals unsymmetry make them unstable.
What are spiranes in organic chemistry?
Policyclic non-aromatic (alicyclic) compounds, I believe.
Is helium unstable and also radioactive?
Helium is extremely stable and non radioactive
Does uranium exist in a stable non-radioactive form?
All the isotopes of uranium are radioactive and unstable.
Is a noble gas chemically reactive and unstable?
no, it's the complete opposite they are stable and non reactive
Is fluorine a reactive or stable element?
fluorine stable fluorine diatomic is unstable
Does the double ring in purines hold it together?
Aromatic rings tend to be more stable than non-aromatic rings, if that's what you're asking. I'm not quite sure what the question means.
What is the difference between aromatic and aliphatic compounds?
Aliphatic compounds could be straight chain structures [Acyclic] like alkanes or cyclic structures, like cycloalkanes. Aliphatic compounds are hydrocarbon chains - strings of carbon atoms connected to each other with hydrogen atoms hanging off the sides of the chain. one exception for the definition of aliphatic side chain is Proline which also has aliphatic side chain but the its side chain is bonded to both carbon and nitrogen. Aromatic compounds have benzene ring (older notion). Aromatic compounds are those which follow Huckel's rule. (4n + 2pi) rule. They have the general formula: CnH2n-6 [where n is equal to or greater than 6] Aromatic compounds are rings - so take the chain and connect the two ends together to form a continuous loop.
What is the difference between radioactive and non radioactive materials?
Radioactive substances are unstable as a result of the extra neutrons present in the nuclei of the substance. Non radioactive substances are stable.
What is the difference between a non-radioactive substance and a radioactive substance?
Radioactive substances are unstable as a result of the extra neutrons present in the nuclei of the substance. Non-radioactive substances are stable.
What types of product is perfume?
Perfume extract, or simply perfume (extrait): 15-40% (IFRA: typical 20%) aromatic compoundsEsprit de Parfum (ESdP): 15-30% aromatic compounds, a seldom used strength concentration in between EdP and perfumeEau de Parfum (EdP), Parfum de Toilette (PdT): 10-20% (typical ~15%) aromatic compounds, sometimes listed as "eau de perfume" or "millésime." Parfum de Toilette is a less common term that is generally analogous to Eau de Parfum.Eau de Toilette (EdT): 5-15% (typical ~10%) aromatic compoundsEau de Cologne (EdC): Chypre citrus type perfumes with 3-8% (typical ~5%) aromatic compounds. "Original Eau de Cologne" is a registered trademark.Perfume mist: 3-8% aromatic compounds (typical non-alcohol solvent)Splash (EdS) and aftershave: 1-3% aromatic compounds. "EdS" is a registered trademark.
Are there more non -elements than elements?
I am not sure what you mean by 'non elements'.ALL matter is made up of elements - there is no such thing as a 'non element'.Elements can however join up to form compounds and the number of compounds that can be formed far exceeds the number of elements that comprise them.
