this resonance structure helps C6H5O- to disperse(分散)the -ve charge on the oxgen atom.(即是个负电荷会在个aromatic ring 上走来走去) This me that the chance for the ionized H-atom to rebine with the -ve charged oxygen atom will be lower. (负电荷会吸引正电荷的离子
但当负电荷被分散时
负电荷吸正电荷的离子会无禁应
因为个负电荷已不是在氧分子这里了.所以化学平衡向右移) Why the existance of resonance structure can give a higher stability? Resonace structure lowers the total potential energy of the cpd
making the cpd more stable. This can be tested by enthalpy of bustion. The more stable the cpd
the less heat energy will be given ring the bustion process. You will find the wer by paring graphite with diamond ring bustion process. -ve = negative cpd = pound I hope you will find my wer helpful.
