Funny. I have recommended this website (https://www.stolaf.edu/depts/chemistry/courses/toolkits/247/js/names/dnames.htm https://www.stolaf.edu/depts/chemistry/courses/toolkits/247/...) to many of my students to help them practice naming alkyl substituted alkanes. The web-page has an "analyze" button that does a great job showing students how to find the longest carbon chain, which is then used to help determine the molecule's IUPAC name. I've always wondered who was behind the site that I had recommended, but I was never curious enough to poke around and answer my own question. When I saw "hack-a-mol" and stolaf.edu, I thought, "okay, must be the same person." People like this (his name is Bob Hanson: https://www.stolaf.edu/people/hansonr/ https://www.stolaf.edu/people/hansonr/) are hidden gems. He's probably not super-famous, but he's made many great tools and I can only imagine that his students have benefited tremendously from his passion and skills.
