Question

CH2OH.CHOH.CH2OH name I.U.P.A.C

Answer 1

This is obviously Glycerol. If we want specify its IUPAC name, firstly, we should look to the length of chain. It has three Carbon (C) atoms. So, Parent, shows how many carbons for IUPAC naming, should be Propan. After this, we can determine functional groups. There are three Hydroxyl (OH-) groups. When there was a hydroxyl (OH-) group, Suffix and Prefix identified in here. Suffix, is the last side of the IUPAC name, shows what is the primary functional group. Also Prefix, is the first side, shows where and what are the substituents.

Answer 2

Answer:

The IUPAC name of the given compound is Propane-1,2,3-triol.

Explanation:

• As we know the IUPAC nomenclature rules, we first look at the number of Carbon atoms, identify the parent chain and name it.
  We get 3 carbon atoms. That makes the root word 'Propan-'
• Next, we determine the functional group.
  Here, we find 3 $OH^-$ (hydroxyl) groups.
• So, we identify the prefix and the suffix.
  There is no prefix for this compound.
• So, we identify the suffix as alcohol group, with suffix '-ol'.
• But because there are 3 of these groups, we denote them as 'triol'.
• Next, we denote the Carbon atoms the functional groups are attached to.
  In our case, it is 1, 2 and 3.

Thus, we get our compound's name as Propane-1,2,3-triol.
