Give examples of compounds that contains alcoholic group.

C5H11OH, C6H13OH, C10H21OH are examples of alcoholic groups.

Alcohols

Alcohols are derivatives of hydrocarbons in which an –OH group has replaced a hydrogen atom. Although all alcohols have one or more hydroxyl (–OH) functional groups, they do not behave like bases such as NaOH and KOH. NaOH and KOH are ionic compounds that contain OH– ions.

  • Ethanol, CH3CH2OH, also called ethyl alcohol, is a particularly important alcohol for human use.
  • Alcohols containing two or more hydroxyl groups can be made. Examples include 1,2-ethanediol (ethylene glycol, used in antifreeze) and 1,2,3-propanetriol (glycerine, used as a solvent for cosmetics and medicines)
  • When a hydroxyl group is attached directly to a benzene ring, the compound is called a ‘phenol’.
