What's the difference between alcohol and hydroxyl?

Alcohol


Definition:

  • (n.) An impalpable powder.
  • (n.) The fluid essence or pure spirit obtained by distillation.
  • (n.) Pure spirit of wine; pure or highly rectified spirit (called also ethyl alcohol); the spirituous or intoxicating element of fermented or distilled liquors, or more loosely a liquid containing it in considerable quantity. It is extracted by simple distillation from various vegetable juices and infusions of a saccharine nature, which have undergone vinous fermentation.
  • (n.) A class of compounds analogous to vinic alcohol in constitution. Chemically speaking, they are hydroxides of certain organic radicals; as, the radical ethyl forms common or ethyl alcohol (C2H5.OH); methyl forms methyl alcohol (CH3.OH) or wood spirit; amyl forms amyl alcohol (C5H11.OH) or fusel oil, etc.

Hydroxyl


Definition:

  • (n.) A compound radical, or unsaturated group, HO, consisting of one atom of hydrogen and one of oxygen. It is a characteristic part of the hydrates, the alcohols, the oxygen acids, etc.

Example Sentences:
