Heptane Memes

Normal humans see numbers like 7 and 4. Chemists see structural formulas for heptane and butane with methyl groups attached in different configurations. The punchline? "It's the same molecule." That's peak organic chemistry humor right there. To a chemist, these aren't just digits but molecular structures hiding in plain sight. Next time you write your phone number, remember some poor chemistry grad student is seeing alkanes everywhere.
