No it does not obey the 4N+2 electrons... it has 4 pi electrons... it is anti aromatic however the ion is aromatic which explains its relatively low pka value of 15-16 which is on par with alcohols which are generally 16-18pka
No.
An aromatic compound contains at least one benzene ring, which is a 6-carbon ring in which all the carbon atoms are sp2 hybridized. The carbon atoms in cyclohexane are sp3 hybridized.
Aromaticity have to follow Huckel Law where the number of rings should equal to n in which 4n+2=num of pie bonds. in cyclooctatetraene. there are 4 double bonds thus 8 pi bonds thus n value comes to 6/4 which shows that it is non-aromatic. n should be an integer (num of rings).
No. To have an aromatic molecule it must have a conjugated system with Huckel's number of pi electrons which can be found using this equation: 4n+2 where n can be any integer.
Cuclopropeneyl cation is aromatic. It complies to all criterias of aromaticity:
it is
- planar
-cyclic
-4n+2 pi electrons (Huckel's Rule)
-etc...
Because the pi electrons of the bonds are delocalised.
An anion is a negative ion, i.e. one which is attracted to the anode during electrolysis. It's a particle, so it can't contain a liquid.
Well the difference will be in the type of bond formed as a result. The bond would be Ionic in case of polarized anion and Covalent in case or unpolarised anion.The related link below also talks about the size of the anion and charge density in determining the bond type.
Chloride would be a negative ion in sodium chloride dissolved in water.

Cyclopentadiene is a non aromatic compound but cyclopentadiene anion is aromatic in nature due to, 1- six pi electrons and 2- process of resonance so to stabilized itself as the aromatic anion the cyclopentadiene removes on hydrogen ion and behaves like an acid.
Cyclopentadienyl Nickel Nitrosyl
Mahmoud M. Al-Ktaifani has written: 'Novel chemistry of the aromatic P3C2tBu2 anion and its derivatives'
Aromatic compounds are resonance stabilized. Hence if a compound is aromatic it is more stable. The main thing to note here is that AROMATICITY GIVES STABILITY TO A COMPOUND. Therefore cyclopropene is an aromatic compound and hence is more stable than propene.
Ferrocene is an organometallic compound because it has two rings of cyclopentadienyl on opposite sides of a metal atom.
polyatomic anion
No, cyclohexanol is not an aromatic compound since it does not exhibit aromatic resonance stabilization (like benzene). Refer to Hückel's rule for clarification of the definition of an aromatic compound.
aromatic
Yes. naphthalene is aromatic
Glucose is not an aromatic. It has no smell whatsoever.
it not aromatic because there is no conjucted carbon
