  • Quelles sont les espèces Reactives de la 2,4-DNPH ?

    La 2,4-DNPH permet de mettre en évidence n'importe quelle liaison carbonyle.
    On introduit ce réactif dans quatre tubes contenant du 3-méthylpentan-3-ol, du 2-méthylpentan-2-ol, du 3-méthylpentan-2-ol et du 2,2-diméthylpentanol.

  • Comment se manifeste le test positif à la 2,4-DNPH ?

    On mélange le composé organique à tester avec de la 2,4-DNPH.
    Si un précipité jaune-orangé de 2,4-dinitrophénylhydrazone apparaît, le test est positif et le composé organique est soit un aldéhyde, soit une cétone.
    Sinon, le test est négatif, et le composé organique n'est ni un aldéhyde, ni une cétone.

  • La 2,4-DNPH permet de mettre en évidence n'importe quel groupe carboxyle.
    On introduit ce réactif dans quatre tubes contenant du 2-méthylbutan-1-ol, du 2-méthylbutan-2-ol, du butan-2-ol et du du butan-1-ol.
