When the hydroxyl group, like in the image below, is attached to a carbon compound, the organic compound is a(n) a hydrogen atom covalently bonded to an oxygen atom, which is covalently bonded to a carbon in the carbon chain. carboxylic acid. alcohol. ether. ketone.

            The organic compound is an Alcohol.

Explanation:
                   Alcohol are class of organic compounds which are derived from water molecule. When one hydrogen atom in water molecule is replaced by an alkyl group it forms alcohols. i.e.

                           H-O-H  +  R    →    R-O-H  +  H

In above equation, R-O-H is the general formula of alcohols.

Examples:
                 CH₃-O-H    Methanol

                 CH₃-CH₂-O-H     Ethanol

                 CH₃-CH₂-CH₂-O-H     Propanol

                 CH₃-CH₂-CH₂-CH₂-O-H      Butanol

                 CH₃-CH₂-CH₂-CH₂-CH₂-O-H      Pentanol

The correct answer is d
