The names of four esters are listed. methyl propanoate ethyl propanoate propyl propanoate butyl propanoate Esters are a family of organic compounds with similar chemical properties. They can be represented by the formula CnH2nO2. State the name given to a family of organic compounds with similar chemical properties. Explain why members of a family of organic compounds have similar chemical properties. State the name given to a formula such as CnH2nO2. Determine the value of ‘n’ in butyl propanoate. All four of the esters in the list are liquids at room temperature. Name the technique used to separate ethyl propanoate from a mixture of the four esters. All four esters can be made by reacting different alcohols with the same substance. Name this substance and draw its structure. Show all of the atoms and all of the bonds. name structure  Name the alcohol used to make methyl propanoate. Other esters, not in the list, have the same molecular formula as propyl propanoate, but different structures. State the term used to describe substances with the same molecular formula but different structures. Name two esters with the same molecular formula as propyl propanoate.  Polyesters can be made from the two different molecules shown. C O H and O H O C O O H H O Complete the diagram to show a section of the polyester made from these two molecules. Include all of the atoms and all of the bonds in the linkages.  Name the type of polymerisation that takes place when this polymer forms. Name a polyester.
