Fórmula molecular

Fórmula Molecular, na Química, é aquela que descreve o número de átomos numa molécula. [1]

Da fórmula molecular

C3H6O

pode-se concluir que numa mole desta substância existem 3 moles de átomos de carbono, 6 de hidrogénio e 1 de oxigénio.

Porém, esta fórmula pode se referir a cinco substâncias diferentes:

Uma cetona: Propanona (Dimetil Cetona ou Acetona) (H3C—CO—CH3)H3C—CH2—CHO) [2]

Um aldeído: Propanal (Propanaldeído) (H3C—CH2—CHO) [3]

Um Éter: Metoxieteno (H3C—O—CH=CH2)

Um Álcool: Prop-2-en-1-ol (H2C=CH—CH2OH) ou Ciclopropanol

Pode-se observar que a fórmula molecular pode gerar, às vezes, engano, quando se necessita determinar a substância. Porém ela pode ser muito útil quando se deseja simplificar equações de reações químicas. Fórmulas mais completas que a molecular, mais utilizadas na química orgânica são a fórmula estrutural e a fórmula estrutural eletrônica ou de Lewis.[1]
