Suggest a scheme to convert alcohol into an acid with one more carbon atom.

Explanation

To convert an alcohol into a carboxylic acid with one additional carbon atom, we can follow these steps:

### Step-by-Step Solution:

1. **Starting Material**: Begin with the alcohol, which we can denote as R-OH, where R is the carbon chain of the alcohol.

2. **Convert Alcohol to Alkyl Halide**: React the alcohol (R-OH) with a reagent such as hydrogen chloride (HCl) to convert it into an alkyl halide (R-X). The reaction proceeds as follows:
\[
