nogen som gider og se om jeg er på det rette spor?

a) navngiv de fire forbindelser :

CH₃CHOHCH₂CHOHCH₃ = 2,4-dihydroxypentan

CH₃COCH₂CHO = 3-carboxy-butan-1-al

CH₃(CH₂)₂COONa = Natriumbutanat 

CH₃CH₂OCH₂CH₃ = diethylether

b)
                                   O
                                    ||
            forbindelsen CH₃C-O-CH₂CH₂CH₃

                           edddikesyre-propyl-ester = propyl-ethanat

navngiv de organiske forbindelser i reaktionsskemaet:

                     CH₃COOCH₂CH₂CH₃ + H₂O <--->  CH₃COOH + CH₃CH₂CH₂OH
                            propyl-ethanat                                ethansyre           propanol

c)
                     RCOOH _(aq)   +   NaOH _(aq)   --->   RCOONa _(aq)   +   H₂O _(l)

tusin taaak for hjælpen :)

identifikation af monocarboxylsyren:

                antal mol syre = antal mol NaOH

                n_s = (0,0668 L) · (1,01 mol/L) = 0,067468 mol

                molmasse = (5,00 g) / (0,067468 mol) = 74,1092 g/mol

                formel
                            C_nH_2n+1COOH = C_xH_2xO₂

hvoraf
                sum({x,2x,2}*{12.011,1.008,15.999}) = 74.1092

                14.027x + 31.998 = 74.1092

                x = 3

dvs
                C₃H₆O₂   eller   C₂H₅COOH   propansyre

rettelse:
               CH₃COCH₂CHO = 3-carboxy-butan-1-al   rettes til    CH₃COCH₂CHO = 3-carbonyl-butan-1-al

b)
                                       O
                                        ||
            forbindelsen CH₃C-O-CH₂CH₂CH₃

                           edddikesyre-propyl-ester = propyl-ethanat

c)

     således kan
                            RCOOH _(aq)   +   NaOH _(aq)   --->   RCOONa _(aq)   +   H₂O _(l)

     specificeres
                            C₂H₅COOH _(aq)   +   NaOH _(aq)   --->   C₂H₅COONa _(aq)   +   H₂O _(l)

                                       _{propansyre                natriumhydroxid           natriumpropanat}
