Question

Which has higher Resonance energy and why?​

Answer 1

Answer:

pyridine is lower energy than payroll

Explanation:

pyridine has more carbon atoms and according to sasche mory principle pyridine has less torisnall strain

Answer 2

Answer:

Explanation:

Phenanthrene has more resonance energy than anthracene. because:-

The phenanthrene has benzene-like moieties at the extremeties while anthracene has benzene-like moiety in the middle. Thus phenanthrene has greater aromatic characters due to presence of two benzene-like moieties at extreme ends thus being more stable and having greater resonance energy.

Anthracene has one benzene-like moiety which can appear in any of the three rings giving the two structures as given above. Anthacene has lesser aromatic characters and thus is less stable and has lesser resonance energy.

Thus phenanthrene has greater resonance energy than anthracene.
