Question

Why is aspirin achiral?

Answer 1

Because it contains no chiral centres.

Explanation:

Aspirin, acetylsalicylic acid ASA contains no chiral centres. As organic molecules go, it is reasonably simple, and can be synthesized cheaply, and in vast quantities. Given its utility as an analgesic and, more importantly, as a long term, low dose medication to prevent heart attacks, and strokes, this is really a stroke of luck.
