Why does having equivalent resonating structure give more stability?

If we take a phenolate ion ($\ce{C6H5O-}$) and an acetate ion ($\ce{CH3COO-}$) which one would be more stable? Although the Phenolate ion has more(4) resonating structure compared to acetate ion(2), ...

Can polyatomic ions (CO3,PO4,SO4,NO3) be considered conjugated systems?

From my perspective these resonance structures allow these specific polyatomic ions to act as Donor-Acceptor molecules. Many donor-acceptor molecules also tend to be Conjugated systems because they ...

Is acetate a weak base due to its resonance structure?

I just read that acetic acid is an exception to the general idea that the conjugate base to a weak acid is a strong base. The example says that the conjugate base of a weak acid will only be strong ...
