toluene structure?

Question

In the structure of toluene, a circle exists inside it's cycle.
What does this circle represents?

Answer 1

The "circle" represents aromaticity, i.e. alternating double and single bonds. The "circle" is *not* an oxygen atom :-)

Answer 2

Toluene is a substituted benzene ring with methyl group, the circle inside the ring is not related to toluene , it means the resonance of the benzene ring ie the bond are conjugated and not localized ,( sorry i can't draw the Kekule' two formula of benzene) , so the circle in an aromatic ring represent the bonds movement at the benzene ring.

Answer 3

ok toluene has a benzene jus add CH3 gp. to it. The circle represents the resonating double bonds inside the benzene ring. Inside the benzene ring the p-orbitals of the carbon atoms present are arranged such that the xtra-electrons ( ones which r not forming bonds) can go around freely in the near-by p-orbitals. thus the un-paired electrons move around freely in the benzene ring. this is resonance , and thats why the double bonds are sumtime represented by a circle inside which shows complete resonance.

Answer 4

The circle represents the delocalised electrons in the benene part of the toluene molecule. The electrons are said to be delocalised because the are always resonating aroung the benzene ring.

Answer 5

the circle represents the double bonds in water. because benzene is symmetrical, the double bonds will rotate. since toluene is just benzene with a methyl group, toluene's double bonds will rotate as well.

Answer 6

Toluene is an organic compound. The molecular structure can be seen in the Wikipedia article below. Basically, it is a benzene ring with one methyl group.

Answer 7

The circle inside the hexagon is short hand for alternating double bonds. So if you were to write it the otherway, you would see, a single line on one side, and two double lines on each side adjacent to that sigle bond. It goes single-double-single-double-single-double and the two ends are attached.

Than you also so the methyl group (-CH3) hanging off of it. I you don't see anything, it's just benzene.

Answer 8

Represents a benzene ring.
Presented this way to indicate that the double bonds are not localized, but are "shared" all the way around, making (in essence) six (one and a half strength) bonds.

Answer 9

The circle is a standard way of depicting shared electronic bonds between (in this case) carbon atoms.

Answer 10

The circle is used to represent resonance.
