And let's go ahead and draw the other resonance structure. So let's go ahead and draw a resonance, double-headed arrow here,Īnd when you're drawing resonance structures, you Those pi electrons out, onto the top oxygen. We're gonna take these two pi electrons here, and move To form a double-bond between this carbon and that oxygen. Oxygen, and move that lone pair of electrons in here, And so, what we're gonnaĭo, is take a lone pair of electrons from this More, and here's an example: This is the acetate anion,Īnd this dot structure does not completelyĭescribe the acetate anion we need to draw another Dot structures is not enough to completely describeĪ molecule or an ion, sometimes you need two or
