We’ve learned how to name simple alcohols before, but now we are moving to polyols.

 

Note: I am moving away from the term glycol, and using polyols instead, since the term glycol is not specific enough. 

Concept #1: How to name polyols.

In Summary:

Polyols with two hydroxyls are called diols, and polyols with three hydroxyls are called triols.

  • Always give most priority to the –OH group.

Example #1: Provide the correct common and IUPAC name of the following alcohol.

Note: The molecule should be named trans-1,3-cyclohexanediol. 

 

There are other possible name variations that are also acceptable. Here are just a few: (R,R)-cyclohexane-1,3-diol, (1R, 3R)-1,3-cyclohexanediol

Example #2: Provide the correct common and IUPAC name of the following alcohol.
