Unformatted text preview: stabilizes the anion. For this reason, the thiol is more acidic than the alcohol. The thiol that also contains a chlorine substituent is more acidic than the thiol that lacks a chlorine substituent, due to the inductive effect caused by the electronegative chlorine atom. (c) E x p l a n a t i o n : H As(CH 3 ) 2 H As(CH 3 ) 2 H H N(CH 3 ) 2 2 3 1 Considering the same element, positively charged molecules are more acidic than neutral molecules (the conjugate base is a neutral molecule which is more stable than an anion). As stated above, when moving down a column, acidity increases, because localization of the negative charge on a larger atom stabilizes the conjugate base anion....
