To compare the acidity of two organic acid, we must the y of their conte bases. The more stable the conjugate base, the stronger the acid. To determine if the conte base is stable, we must follow the below less Negative charges are more stable on trov o LF, Br Larger atoms with negative charge more stable Negative changes preferoide one s than on more electronegative Negative changes to be placed intoms with the more character so they prefers over...
