Recently, we saw see that a carbocation can be formed from an alcohol substrate in the presence of an acid, and an example of such a reaction is given below. Draw the carbocation intermediate that is expected in the SN1 reaction shown. If the carbocation is resonance-stabilized, draw all the significant resonance structures (hint: draw resonance structures that have only one formal charge).
