Ethanol is technically an alcohol hydrocarbon, if we're getting into the weeds on semantics.

What is an "alcohol hydrocarbon"? Alcohol isn't a hydrocarbon. As already pointed out a hydrocarbon is comprised entirely of hydrogen and carbon.

Alcohol hydrocarbons are hydrocarbons with an alcohol group attached (see the diagram at https://en.wikipedia.org/wiki/Hydroxy_group) The simplest would be methanol, from methane. Any organic chemist would know what you meant, although it's not really correct terminology. IIRC the hydrocarbon would be called an 'alkyl group'.
