Multiple Choice

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   ?

• In the  C6H6  molecule, all the bonds between the carbon atoms have the same length.

• Because of variable bonding between its carbon atoms,  C6H6  is a good conductor of electricity.

• The bonds between carbon atoms in  C6H6  are unstable, and the compound decomposes quickly.

• The C6H6 molecule contains three single bonds between carbon atoms and three double bonds between carbon atoms
