Organic chemistry, tseem hu ua chemistry ntawm carbon compounds, yog ib qho kev tshawb fawb uas kawm txog cov muaj pes tsawg leeg, cov qauv, cov khoom, kev npaj thiab kev siv cov organic tebchaw, thiab yog ib ceg tseem ceeb ntawm chemistry. Carbonaceous tebchaw yog hu ua cov organic tebchaw vim hais tias yav tas los chemists ntseeg hais tias xws li tshuaj yuav tsum tau tsim los ntawm cov kab mob nyob, tab sis nyob rau hauv 1828, German chemist Friedrich Wühler ua tau zoo nyob rau hauv synthesizing urea (ib biomolecule) thawj zaug nyob rau hauv lub laboratory, thiab txij thaum ntawd los. organic chemistry tau nthuav dav dhau qhov kev txhais lus ib txwm siv rau chemistry ntawm hydrocarbons thiab lawv cov derivatives.
