Question

the diagram above shows two resonance structures for a molecule of c₆h₆. the phenomenon shown in the diagram best supports which of the following claims about the bonding in c₆h₆? a in the c₆h₆ molecule, all the bonds between the carbon atoms have the same length. b because of variable bonding between its carbon atoms, c₆h₆ is a good conductor of electricity. c the bonds between carbon atoms in c₆h₆ are unstable, and the compound decomposes quickly. d the c₆h₆ molecule contains three single bonds between carbon atoms and three double bonds between carbon atoms.

Explanation:

Resonance structures indicate that the actual bonding in benzene ($C_6H_6$) is a hybrid of the resonance - forms. In benzene, due to resonance, all carbon - carbon bonds have the same length, which is an intermediate between a single and a double bond. Benzene is a non - conductor of electricity as it has no free electrons for conduction. It is a stable compound and does not decompose quickly. The resonance hybrid structure means there are no distinct single and double bonds as shown in the resonance forms.

Answer:

A. In the $C_6H_6$ molecule, all the bonds between the carbon atoms have the same length.
