Is benzoquinone aromatic?
No - although it has sufficient electrons to obey the Huckel rule (4n+2) pi electrons. The two olefins in the ring are cross-conjugated through the carbonyl groups. The lack of proper conjugation precludes aromaticity. The non aromaticity is evidenced by different bond-lengths around the ring
What are non -stoichiometric compounds?
The defect which disturb the stoichiometric of the compound is called non-stoichiometric compounds.
Why pyrol is aromatic?
because it obeys huckle rule of aromaticity.
What are non-metals in the nitrogen family?
elements and compounds
Examples of ionic and covalent compounds?
Ionic compounds: NaCl, KOH, CuSO4, etc. Any compound containing a metal and a non-metal. In ionic compounds, metals have positive ions (they lose electrons to the non metal) and non-metals have negative ions (as they gain electrons from the metal) Covalent compounds: CH4, BF3, NH3, all hydrocarbons/ all compounds containing only non-metals.
What is a benzenoid?
A benzenoid is a compound with an electronic structure analogous to that of benzene.
What is quasi aromaticity?
Quasi aromatic compounds are ionic in nature, there is a presence of counter ion e.g. when tropone react with HClO4 quasi aromatic compound is formed.
What is aromaticity?
<p><p>Benzene and other organic compounds which resemble it in chemical behaviour exhibit certain characteristics properties which distinguish them from aliphatic compounds. Such characteristics properties called aromaticity. **Ammie**
Illustrate the difference between aromaticity and antiaromaticity with appropriate examples?
Illustrate the difference between aromaticity and antiaromaticity with appropriate examples?
How is huckel rule applied in determining aromaticity?
Huckel's rule is used in aromaticity by stating that monocyclic systems are aromatic. This will happen if there are delocalized electrons.
How do you make isomers in a benzenoid ring in c7h12?
isomer dari C7H12

Are non binary compounds and polyatomic compounds the same thing?
yes
Which chromatography to separate non volatile compounds?
High performance liquid chromatography is used to separate non volatile compounds
