Why are resonance hybrid supposed to be considered to be stable?

[holadi]

why are they resonance hybrid considered to have a lower energy state than other resonance hybrid?does the delocaliazation of electrons cause?if yes then y? ..help me ASAp

I just read the wikipedia page describing the phenomena (see: http://en.wikipedia.org/wiki/Resonance_Hybrid). I think the answer is yes, but am unable to answer why. Sorry. I hope someone else is online to help you

Perhaps if you were to rephrase your question to make sense is could be answered.

 

What do you actually mean please?

I think he is saying why the hybrid is more stable than the resonance structure.

for example benzene's structure is intermediate between the other resonance structures and stable. but why?

I know the fact since high school but I didn't read any thing why delocalization stabilize it.

When I google it I found this link check it out... this might help.
