Kan du også klare denne:

Tegn strukturformel for:

- Methansyremethylester

- Methansyreoctylester

- Butansyreethylester

             ...vis først at du véd, hvad en ester er   :-)

          
                                      O                                                 O
                                       ||                                  kat.          ||
                                R₁ - C - OH     +    HO-R₂    --->   R₁- C - O - R₂   +   H₂O

                              alkansyre                alkanol                   ester

                                          O
                                           ||
                                     H - C - O - CH₃

                                ^{methansyremethylester}

                                   O
                                    ||
                              H - C - O - C - C - C - C - C - C - C - C

                                        ^{methansyreoctylester}

                                                  O
                                                   ||
                                 C - C - C - C - O - C - C

                                       ^{butansyreethylester}
                                           

Jeg har ik så meget styr på det her, men hvordan fandt du ud af det
