WebNow the negative charge on the conjugate base can be spread out over two oxygens (in addition to three aromatic carbons). The phenol acid therefore has a pK a similar to that of a carboxylic acid, where the negative charge on the conjugate base is also delocalized to two oxygen atoms. The ketone group is acting as an electron withdrawing group – it is … WebNov 20, 2024 · How does charge affect acidity? Charges prefer to be on larger atoms than on smaller atoms. The much larger iodine atom allows the negative charge to delocalize over a larger space than does the much smaller fluorine atom, and thus makes hydrogen iodide more acidic. The effect that atom size has on acidity is shown here.

WebWhat contributes to acidity? Predictably, this effect is going to be related to two major factors: 1) the electronegativity of the element (the more electronegative, the more acidic) and the distance between the electronegative element and the negative charge. How do orbitals affect acidity? WebApr 26, 2015 · Yes, the more stable the conjugate base (A-), the more reactive the acid will be, thereby favoring dissociation. HA ----> H+ + A-.
