Answer 1

The correct answer is C₂H₅OH

Explanation:

Alcohols are organic compounds in which a hydroxyl group (-OH) is attached to a carbon atom. The general formula for alcohols is R-OH, where R represents an alkyl group.
Ethanol (C₂H₅OH) is the most common type of alcohol, and it is widely used in beverages, as a solvent, and in the pharmaceutical industry.
The molecular formula of ethanol is C₂H₅OH, which indicates it consists of two carbon atoms, six hydrogen atoms, and one oxygen atom, with the hydroxyl group attached to one of the carbon atoms.

Other Options:

C₂H₅: This formula represents an ethyl group, which is an alkyl group derived from ethane (C₂H₆) by removing one hydrogen atom.
C₂H₅COOH: This is the chemical formula for propanoic acid, a carboxylic acid. It contains a carboxyl group (-COOH) instead of a hydroxyl group.
