Understanding the $C_6H_6$ Formula

The question asks to identify the chemical compound represented by the molecular formula $C_6H_6$.

Identifying the Compound $C_6H_6$

The formula $C_6H_6$ specifically represents the organic chemical compound known as Benzene. Benzene is an aromatic hydrocarbon with a ring structure consisting of six carbon atoms, each bonded to one hydrogen atom.

Analyzing the Options

• Option 1: Hydro Carbon - This is a general classification for compounds containing only hydrogen and carbon. While Benzene is a hydrocarbon, this option is too broad.
• Option 2: Hydrochloric Acid - This is an acid with the chemical formula $HCl$, which is completely different from $C_6H_6$.
• Option 3: Benzene - This matches the chemical formula $C_6H_6$.
• Option 4: Toluene - Toluene is also an aromatic hydrocarbon, but its formula is $C_7H_8$ (Benzene ring with a methyl group attached).

Conclusion

Based on the specific molecular formula $C_6H_6$, the correct identification is Benzene.
