Question

Chemical name (IUPAC) of ${{(C{{H}_{3}})}_{3}}COH$ is

Answer 1

Hint: The answer to this question includes numbering of terminal carbon atoms which is near to the highest preferable functional group (here –OH group) and writing the names accordingly.

Complete step by step solution:
In the lower sections of chemistry which includes the basic concepts, we have come across the IUPAC (International Union for Pure and Applied Chemistry) naming of chemical compounds which deals with naming of organic compounds.
- According to this rule, the name of the compound is written out with the substituents in alphabetical order which is then followed by the base name,
- Therefore based on this rule the numbering of the compound can be done starting from the numbering of a carbon atom containing a functional group.
- Here, only one functional group is present in the provided question which is attached to the middle carbon atom. The structure for this compound can be written as,

Here, the first carbon atom and the third carbon atom are at equal parts from that of the second carbon atom. The middle carbon atom contains two groups attached, that is, one is the methyl group and the other is the alcoholic group. Thus, according to the number assigned, we can write the chemical name of the compound as , 2 – methyl propan- 2- ol

Therefore, the chemical name of the compound ${{(C{{H}_{3}})}_{3}}COH$ is 2 – methyl propan -2- ol.

Note: The chemical name of the compound can be in the common name form which is near to that of IUPAC name. Do not get confused about which name is the common and which is the IUPAC name. IUPAC naming consists of numerical and common name does not.
