Organic chemicals, by definition, contain hydrogen, carbon and oxygen only, but this definition covers many thousands of compounds from simple methane (CH4) to biomolecules with very high molecular weights (e.g. starches which can contain thousands of glucose sub-units). The impact of organic chemistry on modern human life is impossible to overestimate. If you allow the definition to include the substitution of nitrogen, phosphorus and sulphur, then you include almost all of the biochemistry of life. Some organic compounds are hazardous to human health and the biosphere and can be dangerous even in small quantities.
