A major in Chemical Engineering already makes a statement that you've had a good foundation in Chemistry from your undergrad. This means general chem, organic, analytical, and maybe even physical. Most of the time a chem minor is only one or two classes away, but you should only take the additional chemistry courses if you love chemistry (which ChemE's USUALLY do) and want to. Nobody is going to be impressed with a Chem minor as a ChemE major.
And since you seem to be an incoming freshmen, I'll go ahead and repeat the words that's been said by every chemE since antiquity. Chemical Engineering isn't much chemistry. Most ChemE's have a love for chemistry, and it's certainly a subject that you'll get to take quite a bit of, but it won't be very vital in your major classes. Chemical Engineering is a broad discipline that exposes you to a lot of different fields. Chances are good you'll also have to take at least 2 or 3 biology/biotechnology classes.
