It is a homework question (never been a fan of chemistry!). I am studying aromatherapy and have been asked to draw the carbon skeleton of an isoprene unit, which I have done. I am then asked to draw two isoprene units to form an acyclic chain as well as a cyclic chain and then a sesquiterpene and so on. What I want to know is, what are the rules of joining isoprene units? Am I supposed to know how they are drawn by the information given? Is there a pattern?
Aromatherapists teach organic chemistry? I was going to write "Next they'll be accepting double-blind trials". I went to check first, and found that more than one essential oil has been shown to be useful in double-blind trials. Well, well - the things you can learn as a result of reading Last Word! I hope that aromatherapists have the courage to accept double-blind trials for all their treatments.
