Statement-1 : Resonance energy of phenanthrene is more than anthracene...
Statement-1: Resonance energy of phenanthrene is more than anthracene.
Statement-2: Phenanthrene has more aromatic character and more delocalization than anthracene.
To understand the given statements, let's first discuss the concepts of resonance energy, aromaticity, and delocalization.
Resonance energy refers to the stabilization energy gained by delocalizing electrons over multiple atoms in a molecule. It is the difference in energy between the actual molecule and the most stable contributing resonance structure(s).
Aromaticity is a property exhibited by cyclic compounds that have a specific arrangement of π electrons, resulting in enhanced stability. Aromatic compounds possess a delocalized π electron system, where the π electrons are spread out over the entire ring.
Delocalization refers to the spreading out of electrons over multiple atoms or regions within a molecule, leading to increased stability.
Now, let's analyze the statements:
Statement-1: Resonance energy of phenanthrene is more than anthracene.
Statement-2: Phenanthrene has more aromatic character and more delocalization than anthracene.
The given statements are related to the resonance energy, aromaticity, and delocalization of phenanthrene and anthracene. Let's evaluate each statement individually and then their relationship.
Evaluation of Statement-1:
Phenanthrene is a polycyclic aromatic hydrocarbon consisting of three fused benzene rings, while anthracene is a polycyclic aromatic hydrocarbon with two fused benzene rings. Since phenanthrene has more benzene rings than anthracene, it has a larger delocalized π electron system. This larger delocalization leads to increased resonance energy in phenanthrene compared to anthracene. Hence, Statement-1 is true.
Evaluation of Statement-2:
Phenanthrene having more aromatic character and more delocalization than anthracene can be explained based on its structure. The additional benzene ring in phenanthrene provides more π electrons to participate in delocalization, resulting in stronger aromatic character and enhanced stability. Additionally, the presence of more fused rings in phenanthrene allows for greater electron delocalization, leading to more aromatic character and increased stability. Hence, Statement-2 is true.
Relationship between the Statements:
Statement-2 provides a correct explanation for Statement-1. The increased aromatic character and delocalization in phenanthrene compared to anthracene directly contribute to its higher resonance energy. Therefore, Statement-2 is a correct explanation for Statement-1.
In conclusion, both Statement-1 and Statement-2 are true, and Statement-2 is a correct explanation for Statement-1.
