For the addition of HCl to alkenes according to the general equation given in the preceding problem, assume the mechanism involves rate-determining formation of the more stable carbocation (arrow 5 ) and predict the alkyl chloride formed by reaction of HCl with (CH 3)2C=CH2

a. (CH3)2CHCH2Cl

b. (CH3)3CCl 

Provide a mechanism for the following reaction. Be sure to include all intermediates, formal charges and arrows depicting electron movement.

Fill in the box with the product(s) that are missing from the chemical reaction equation. Draw only the predominant regioisomer product or products (i.e. Markovnikov or non-Markovnikov products) and please remember that you must draw the structures of all the product stereoisomers using wedges and dashes to indicate stereochemistry. When a racemic mixture is formed, you must write "racemic" under both structures EVEN THOUGH YOU DREW BOTH STRUCTURES.
