Coucou, 

tout d'abord tu dois chercher quelle est la chaine carbonée la plus longue et la fonction prioritaire. Ici, tu as une fonction carboxylique sur le carbone 1 et donc la chaine carbonée la plus longue comporte 4 carbones d'où "butanoïque". 

ensuite tu vois que sur le carbone 2 tu à un groupement éthyl (CH3-CH2) d'où le nom "2éthylbutanoïque".
