Remember the definition of hypothesis from our earlier section of work -a hypothesis is a tentative explanation that can be tested, and is usually based on previous observations. For example: My hypothesis is that my kids sleep better when I take them on a walk of at least 15 minutes long each day. reishe takes in more suugar 6. Design an experiment to test YOUR hypothesis.

For example, CHCIBII is chiral, but CCl,BrI is achiral because some of the bonded groups are the same. If a chiral carbon atom is present, then that molecule has a non-superimposable mirror image called an enantiomer.
