What is the difference between Clorox and other name brand bleach?

There is somewhere between little and no difference between any brand of bleach. All bleach is basically a solution of a few percent of sodium hypochlorite in water. There my be a bit of sodium hydroxide, but not much. Then there will be any one of a handful of additives that are included to improve the scent. Check the label of the product, and pull up a Material Safety Data Sheet on anything you don't know about but wish to investigate. Everything is there, and if you need help interpreting it, WikiAnswers may be able to help with that.
