[SOLVED] Organic Chemistry

Which about benzene is true?

1. It has alternating single bonds and double bonds.

2. All C-C bonds are of the same length.

3. It is more stable than a hypothetical cyclohexatriene.

4 1 and 3

5. 2 and 3

I said 5, but it also has alternating single and double bonds so I am not sure. Can someone verify please

 

[vaazu]

yes, second and third are right. Benzene doesn´t have alternating single and double bonds, it´s just a way of expressing the molecule. Some electrons, don´t know how many of them are delocalized in benzene so the bonds aren´t single nor double.

Thank you

C-C bond in benzene is somewhat midway between a C=C double bond and a C-C single bond.
