• Alcohol may be represented by the general formula KOH
• The reactivity of alcohols is mainly attributed to the OH group
• This functional group has an inherent acid character shown when the hydrogen is released from the OH bond
• The ease of removal is dependent upon the relative polarization of the OH Bond
• Hydroxyl


  What functional group defines alcohols?
• KOH

  Which general formula represents alcohols?
• Hydroxyl group


  What is the acid character of alcohols attributed to?
• Fermentation of sugars and starches


  How is ethyl alcohol commonly obtained?
• ethyl alcohol

  Primary alcohol is commonly known as
• N-propanol


  Which alcohol is also known as 1-propanol
• 2 butanol


  Which alcohol is also known as secondary butyl alcohol
• 2 methyl 2 propanol

  Which alcohol is also known as tertiary butyl alcohol
• ethyl alcohol.


  It is the alcohol present in the alcoholic beverages.
• chromatic acid test

  Primary and secondary alcohols may be distinguished from tertiary alcohol by the
• aldehyde


  Primary alcohols are oxidized to
• ketones


  while secondary alcohols are oxidized in
• from orange to green.


  indicated by the change in color of the solution from orange to green.
• absence of an alpha hydrogen

  Tertiary alcohols are not readily oxidized by the chromic acid because of the
• lucas test

  To further distinguish the different classes of alcohol, what test is employed
• alkyl chloride

  Tertiary alcohols react immediately to form an immiscible upper layer of
• alkyl chloride


  It is insoluble in the medium and causes the solution to become cloudy before it separates as a distinct layer.
• 5 minutes


  With secondary alcohols, the cloudiness appears after
• monohydroxy or polyhydroxy alcohols.


  Alcohols may also be classified based on the number of OH groups as
• glycerol

  An examples of polyhydroxy alcohol
• glycerol


  The most important triol
• soap


  glycerol is obtained as a by product from the manufacturer of
• acrolein test


  Glycerol is detected by what test?
• pungent color

  Glycerol undergoes dehydration when heated with KHSO4 to form propenol (acrolein) which has a what color?
• moisturizing agent in cosmetic formulation, in tobacco products, and in foods.

  gycerol is used as a what?
• alkyl chloride

  Tertiary alcohols react immediately to form an immiscible upper layer of
