Give various functional isomers of butanol and give their isomeric relations.

Explanation

To find the various functional isomers of butanol (C4H10O) and their isomeric relations, we will follow these steps:

### Step 1: Identify the Molecular Formula
Butanol has the molecular formula C4H10O. This indicates that it consists of 4 carbon atoms, 10 hydrogen atoms, and 1 oxygen atom.

### Step 2: Determine the Functional Groups
Functional isomers are structural isomers that differ in the functional group. For butanol, the primary functional group is the hydroxyl group (-OH), which characterizes alcohols. However, butanol can also be related to ethers.
