Benzene is a cyclic hydrocarbon with the molecular formula C6H6. It is a highly stable compound and exhibits unique properties. In order to understand the given statements, let's analyze each statement individually.
Statement I: Benzene has very high stability than a general triene.
- Benzene is more stable than a general triene, which is a molecule with three double bonds.
- The stability of a molecule is influenced by factors such as bond length, bond strength, and resonance.
- In benzene, the carbon-carbon bonds are shorter and stronger than the typical carbon-carbon double bond found in alkenes.
- This increased bond strength contributes to the stability of benzene.
- Additionally, benzene exhibits resonance, which is the delocalization of electrons across multiple atoms.
- The resonance in benzene allows for the distribution of electron density throughout the ring, making it more stable than a general triene.
Statement II: Benzene is a completely conjugated system.
- Conjugation refers to the presence of alternating single and multiple bonds in a molecule, allowing for the delocalization of electrons.
- In benzene, there are alternating single and double bonds between the carbon atoms in the ring.
- This alternating bond pattern creates a completely conjugated system in benzene.
- The delocalization of pi electrons in the conjugated system contributes to the stability of benzene.
- The delocalized electrons can be thought of as being shared by all the carbon atoms in the ring, resulting in a more stable structure.
Explanation of the correct answer:
- Both Statement I and Statement II are correct.
- Statement II is not the correct explanation of Statement I because it only provides additional information about the conjugated nature of benzene.
- The stability of benzene is primarily due to its unique structure, which includes resonance and the presence of stronger carbon-carbon bonds.
- The completely conjugated system in benzene contributes to its stability but is not the sole reason for its higher stability compared to a general triene.
- Therefore, the correct answer is option 'B' - Both Statement I and Statement II are correct and Statement II is not the correct explanation of Statement I.
