What type of cyclic compound is formed from six carbon atoms with alternating single and double bonds?

The formation of a cyclic compound with six carbon atoms that exhibit alternating single and double bonds leads to the structure known as benzene. Benzene is characterized by its planar, symmetrical ring structure and the presence of resonance, which stabilizes the molecule by allowing the electrons in the double bonds to be delocalized over all six carbon atoms.

This unique arrangement gives benzene its distinctive properties, such as its reactivity and its aromatic character, which is a result of the alternating single and double bonds that create a highly stable ring system. Each carbon in benzene is bonded to one hydrogen atom, resulting in the chemical formula C6H6.

In contrast, the other options either do not possess a cyclic structure (like hexane and hexyne) or do not have alternating single and double bonds (like cyclohexane, which consists only of single bonds). Therefore, the correct identification of the cyclic compound with the specified bonding pattern is indeed benzene.
