A chemist who studies alcohols, which consist of carbon, hydrogen, and oxygen, would most likely be an organic chemist.

Here's why:

* Organic chemistry is the branch of chemistry that focuses on the study of carbon-containing compounds, including their structure, properties, and reactions.

* Alcohols are a specific type of organic compound that contain a hydroxyl (-OH) functional group attached to a carbon atom.

While other types of chemists might have some interest in alcohols, it's the core focus of organic chemistry.
