One out of the five of Huckell's rules tells us that the molecule needs to be fully conjugated in order for it to be considered an aromatic molecule.
Looking at cycloheptatriene you can see that we have three double-bonds, each making two carbons sp2 hybridized. However, the seventh carbon is sp3 (the one that is not bonded to a double bond) so therefore fails Huckell's criteria and can not be considered aromatic.
The cycloheptatrienyl cation; however, converts this sp3-hybridized carbon in to an sp2-hybridized carbon, with an empty p-orbital.
We would then have the following:
1)Molecule needs to be planar - Check!
2)Molecule has 2 or more double-bonds - Check!
3)Molecule is monocyclic - Check!
4)Molecule is fully conjugated - CHECK!
5)Molecule has 4n+2 pi-electrons - Check!
.
This is not an aromatic compound because it didn't satisfy two of the rules for aromaticity.
This ring has 4 double bonds, which means it has 8 electrons participating in pi bonding. According to Huckle's rule of 4n+2 number of electrons (n =0,1, etc), the only allowed numbers would be 2, 6, 10.... The fact that 8 does not fall in this these numbers means it can't be aromatic.
Another rule is that the molecule must be cyclic and planar. While this molecule is cyclic, it still bends to form a boat-like confirmation, thus it is not planar.
Cyclohexene is an unsaturated molecule because contain a double bond and has a ring structure.
No, cyclohexanone is not an aromatic compound. It is a cyclic ketone with a six-membered ring containing a carbonyl group. Aromatic compounds usually contain conjugated pi bonds in a planar ring structure, unlike cyclohexanone.
benzene
This compound is organic, aromatic, fused aromatic, and hydroxylic, among other descriptions.
It is false; aromatic compounds is a category of organic compounds.But many other chemicals have a specific odor but they are not aromatic compounds (of course, in the chemical sense).
An aromatic compound is a compound in organic chemistry which exhibits aromaticity.
Cyclohexene is an unsaturated molecule because contain a double bond and has a ring structure.
No, cyclohexene is not soluble in water. Cyclohexene is a nonpolar compound, while water is a polar solvent. Generally, nonpolar compounds are not soluble in polar solvents like water. Therefore, cyclohexene tends to be immiscible or insoluble in water.
No, cyclohexanone is not an aromatic compound. It is a cyclic ketone with a six-membered ring containing a carbonyl group. Aromatic compounds usually contain conjugated pi bonds in a planar ring structure, unlike cyclohexanone.
benzene
This compound is organic, aromatic, fused aromatic, and hydroxylic, among other descriptions.
The simplest aromatic compound is benzene, which has a molecular formula of C6H6.
no.. One of the contion for a compound to be aromatic is that it should have conjugation..(i.e.ulternate single and double bonds.)
The general formula for an aromatic compound is CnHn, where "n" represents the number of carbon and hydrogen atoms required to satisfy the compound's aromaticity.
Cyclohexene is the hydrogen donor. So, it forms benzene at the conclusion of the reaction. no its not. you have no idea what you are talking about. im the orgomaster not you.
True. An aromatic compound, no matter how bad it is for us, will ALWAYS smell nice and fragrant.
