Chemistry - A Monocyclic 6 Carbon Ring With 6 Double Bonds
Answer : Solution 1: There are several monocyclic \ce C 6 \ce{C6} \ce C 6 isomers. Three of them are pictured below A - the compound you've drawn above, cyclohexahexaene B - cyclohexatriyne C - cyclohexa-2,5-diyne-bis-1,4-ylidene While all of the carbons in these molecules are (more or less) \ce s p \ce{sp} \ce s p hybridized, the molecules are different from one another due to differences in bond lengths and bond angles. For example, all of the bonds in A are exactly the same length due to symmetry, whereas the triple bonds in B will be shorter than the adjacent single bonds. Therefore, A-C are isomers, not resonance structures. Ideally the atoms attached to an \ce s p \ce{sp} \ce s p hybridized carbon form a linear arrangement (180° bond angle) with the central \ce s p \ce{sp} \ce s p carbon, acetylene and the central carbon in allene serve as examples.
