On distingue deux sortes de formules chimiques, les formules brutes et les formules développées. Les formules brutes rendent comptent de la composition des espèces chimiques, c'est-à-dire du nombre d'atomes de chaque élément intervenant dans la constitution des molécules. [...] Deux composés peuvent cependant avoir la même formule brute et être différents [...] et il faut, pour les distinguer, utiliser [...] la formule développée qui indique quels atomes sont liés à quels atomes dans une espèces chimique. 4, record 2, French, - formule%20empirique
