Question

Give the IUPAC name of the following compound.

     

Answer 1

Hint: The hint for you is, this is a compound containing cyclohexane with 3 alcohol groups attached at alternate 1, 3, and 5 positions. Now, just arrange this to get the final IUPAC name.

Complete step by step answer:
Let’s start the IUPAC nomenclature of this compound,

Here in this structure, we can see that its a six-membered ring. So, we use cyclo prefix to indicate the ring structure and hexane for the six carbon atoms. Thus, the name of the ring will be cyclohexane.
Now, we will assign the position of the substituent attached to the cyclohexane.

In this structure, we can see that three -OH groups are attached at the 1, 3, and 5 positions of cyclohexane.
The -OH groups present in this structure are known as alcohol groups. In IUPAC for one -OH group the suffix “ol” is used for its indication. As we already know it has three -OH groups, we will use “triol” as a suffix.
So, the final thing to do is arranging the name in the correct order. That would be,
1,3,5-cyclohexanetriol
Therefore, we can conclude that the correct answer to this question will be 1,3,5-cyclohexanetriol.

Note: There is another compound that looks like this structure given in the question. But it has a benzene ring at the position of cyclohexane. The IUPAC name of this compound is Benzene-1,3,5-triol (Phloroglucinol is the common name).
