元素有机化学是研究元素有机化合物的学科,一般把含有C、H、O、N、S、Cl、Br、I以外元素(称为异元素)的有机化合物称为元素有机化合物,其中把含有异元素与元素碳之间有直接键连的有机化合物称为狭义的元素有机化合物,把一些只含有异元素间接连于碳上的有机化合物称为广义的元素有机化合 Element organic chemistry is the study of elemental organic compounds. Organic compounds containing elements other than C, H, O, N, S, Cl, Br, and I (called isomeric elements) are generally referred to as elemental organic compounds. Organic elements with direct bonds between elemental and elemental carbons are termed narrow elemental organic compounds. Some organic compounds containing only elements indirectly attached to carbon are referred to as generalized elemental organic compounds
