Question: Propan\(-1-\)ol and Propan\(-2-\)ol are: A. tautomers B. functional isomers C. position isomer...

Propan−1−-1-ol and Propan−2−-2-ol are:
A. tautomers
B. functional isomers
C. position isomers
D. metamers

Explanation

Solution

Propan−1−-1-ol is defined as a molecular formula of alcohol with three carbon atoms. It is a colorless liquid and it is an isomer of Propan−2−-2-ol. In pharmaceutical industries, it is used as a solvent. Propan−2−-2-ol is an isopropyl group attached to a hydroxyl group.

Complete step by step answer:
In the tautomerism process, the compounds interconvert themselves, which results in the relocation of a proton. Tautomerization is a process when chemical compounds interconvert each other.
Here we can see that Propan−1−-1-ol and Propan−2−-2-ol are not tautomers of each other. Therefore, option (A) is not incorrect.
Functional isomers are defined as the isomers that have the same molecular formula but they are attached to different functional groups. In this question, both the chemical compounds, that are, Propan−1−-1-ol and Propan−2−-2-ol contain the same hydroxy group.
Hence, option (B) is incorrect.
Position isomers are defined as the isomers that have the same molecular formula, but the functional groups are attached in different locations to each other. In this question we can see that, in Propan−1−-1-ol, the hydroxyl group is attached to the first carbon, whereas, in Propan−2−-2-ol, the hydroxyl group is attached to the second carbon.
Hence, option (C) is correct.
The metamers are defined as the isomers that have the same molecular formula, but atoms are connected in different order. In metamers, different alkyl groups are attached to the same functional group. Therefore, option (D) is also incorrect.

So, the correct answer is Option A .

Note: Isomers are defined as the atoms that contain the same elements but in different arrangements. This phenomenon is known as isomerism.
Isomerism is of two types:
1.Structural isomers: in this isomer, the atoms and functional groups are arranged in different ways.
2.Stereo isomers: in this isomer, the orientation of the compound is different, but has the same formula.
