Write the structural formula of isobutyl alcohol.

Explanation

To write the structural formula of isobutyl alcohol, we can follow these steps:

### Step 1: Identify the molecular formula
Isobutyl alcohol, also known as 2-methyl-1-propanol, has the molecular formula C4H10O. This indicates that it contains 4 carbon atoms, 10 hydrogen atoms, and 1 oxygen atom.

### Step 2: Determine the carbon skeleton
The carbon skeleton for isobutyl alcohol can be constructed by arranging the carbon atoms. Since it is a branched alcohol, we will have a main chain of three carbon atoms (propane) with a methyl group (−CH3) attached to the second carbon.
