How to pronounce“iupac”in English

Despite IUPAC’s best attempts to make organic chemistry nomenclature less confusing, many common names are still used today… probably because “vanillin” is easier to say and put on a bottle than 4-hydroxy-3-methoxybenzaldehyde.

Since IUPAC rules are all about communication, we want to let people know where that double bond is on the chain.

Some rely on IUPAC names, which are not as fun to say so we'll just put them on screen.

As hard as IUPAC tries, their naming conventions haven’t been widely adopted for ethers.

We’ll get into IUPAC ether nomenclature in a later episode, so don’t worry about it now.

And that IUPAC’s rules are really great but some common or trivial names still prevail!

By the time IUPAC came along with standard rules, organic chemistry as a field was already over 100 years old.
