The sec-butyl cation can react as both a Brønsted-Lowry acid (a proton donor) and a Lewis acid (an electron pair acceptor) in the presence of a water-sulfuric acid mixture. In each case, however, the product is different. The two reactions are as follows: H +H (1) CH3-CH– CH2-CH, + H,O CH3-CH-CH2-CH3 sec-Butyl cation (2) CH3-CH-CH2-CH3 + H,0= CH3-CH=CH-CH3 + H;O+ sec-Butyl cation

The sec-butyl cation can react as both a Brønsted-Lowry acid (a proton donor) and a
Lewis acid (an electron pair acceptor) in the presence of a water-sulfuric acid mixture. In
each case, however, the product is different. The two reactions are as follows:
H +H
(1) CH3-CH– CH2-CH, + H,O CH3-CH-CH2-CH3
sec-Butyl cation
(2) CH3-CH-CH2-CH3 + H,0= CH3-CH=CH-CH3 + H;O+
