resonance/mesomerism Explanation: In chemistry, resonance or mesomerism is a way of describing delocalized electrons within certain molecules or polyatomic ions where the bonding cannot be expressed by one single Lewis formula. A molecule or ion with such delocalized electrons is represented by several contributing structures (also called resonance structures or canonical forms). http://en.wikipedia.org/wiki/Resonance_(chemistry) -------------------------------------------------- Note added at 2 days11 hrs (2011-05-30 21:15:04 GMT) Post-grading -------------------------------------------------- Cu placere :) |
