2.2 alcohols, carboxylic acids, and esters

• hydroxyl functional group: a chemical structure found in organic molecules that consists of an oxygen atom bonded to a hydrogen atom

  
• carboxyl functional group: the chemical structure composed of a carbonyl functional group and a hydroxyl functional group chemically joined to the same carbon atom

  
• carbonyl functional group: the functional group formed by the joining of an oxygen atom to a carbon atom by a double bond
• anaphylactic reaction: a life-threatening, severe reaction of the immune system to an antigen that results in severe swelling and may affect the muscles involved in breathing
• plastic: material that can be shaped or moulded with or without the application of heat
• polymer: a large molecule formed by the chemical joining of many smaller molecules
• polyester: a polymer contains many ester functional groups
• esters: organic compounds form by the chemical reaction of carboxylic acid with an alcohol. can be naturally occurring or synthetic products
• bioplastics: an organic polymer produced by plants or bacteria that can be used in place of synthetic polymers to form materials
