Want to eat organic nomenclature problems up for breakfast? Let’s put the system for naming alkanes to work and practice organic chemistry nomenclature with one big, convoluted molecule – I’m calling it “alkane spaghetti”! ????

An IUPAC name for alkane spaghetti

My previous post aimed to help you become a ninja at naming alkanes, and from there you’ll be ready for more complicated structures. Let’s do some organic chemistry nomenclature practice by tackling a big, multi-substituted alkane. I like to call this one “alkane spaghetti”:
