EWG thus stabilize that negative charge because less density helps balance out the negative charge (stronger acid). Edg would destabilize the negative charge ... 28 footballers who look like cartoons WebJul 25, 2012 · In general, if you are ranking acid or bases, use the CARDIO rule. When ranking phenol, that is a benzene with an OH group. You rank its conjugate base and if there is a EWG present that it will increase the acidity by stabilizing the base. Vice versa with EDG. However, you can't assume the EWG and EDG rule for every bases out there.
