#compostos-orgânicos
Question
Defina o que são compostos orgânicos.
Answer
Os compostos ou moléculas orgânicas são, na sua generalidade, as substâncias químicas que contêm na sua estrutura carbono e ligações covalentes C-H, ou substâncias que sejam derivados destas (por exemplo o CCl4, derivado do clorofórmio). Na realidade, quase todos os compostos com carbono pertencem a esta classe de compostos, à exceção dos carbetos (CaC2, Ag2C2, entre outros), carbonatos e bicarbonatos (Na2CO3 e NaHCO3, respectivamente), cianetos (HCN), óxidos de carbono (CO e CO2), assim como os alótropos do carbono grafite e grafeno, diamante e o fulereno. [ 1 ] As moléculas orgânicas apresentam geralmente outros elementos como o oxigénio, nitrogénio, enxofre, fósforo, boro, halogénios entre outros.
