Name the given Phenol organic molecule

    Hi.
    In my chemistry book, one of the questions was to name the given organic molecule. What was given was a benzene ring with a single -OH functional group attached. Immediately, i recognized it as phenol, but i also said its conventional name was benzenol.

    When i turned to the answers, they said it was either phenol or hydroxybenzene.

    My question is this: why should it be named with the prefix for alcohol functional groups, rather than the suffix, since it is the only functional group present?

    Thanks in advance,
    Dan.

    Cyclic compounds like cyclohexane or benzene can be named as the parent hydrocarbon. Hydroxy benzene is the name for phenol just as methyl benzene is the name for toluene.

    Oh, ok. Thanks for that :smile:

    So a cyclohexane with an -OH functional group would be called hydroxycyclohexane?

    It could be. Or it could be called by its other name, cyclohexanol. Welcome to the mad, mad, mad world of organic chemistry.

    Ahh mad indeed.
    So does it just come down to the conventions my teacher wants me to use?

    Welll, it is a little better organized than that. Your teacher would want to teach you what you might encounter out 'there'.
