Berzelius Berzelius Berzelius tau txais txiaj ntsig nrog tshawb pom cov tshuaj lom neeg cerium thiab seleniumthiab nrog ua thawj zaug cais silicon thiab thorium. Berzelius nrhiav tau cerium nyob rau hauv 1803 thiab selenium nyob rau hauv 1817. Berzelius nrhiav pom yuav ua li cas cais silicon nyob rau hauv 1824, thiab thorium nyob rau hauv 1824. https://en.wikipedia.org › wiki › Jöns_Jacob_Berzelius

. Bertholet synthesized benzene thawj zaug.
Leej twg Synthesized benzene thawj zaug?
Benzene tau pom thawj zaug los ntawm tus kws tshawb fawb Askiv Michael Faraday hauv xyoo 1825 hauv cov roj teeb pom kev zoo. Xyoo 1834 German chemist Eilhardt Mitscherlichrhuab benzoic acid nrog txiv qaub thiab tsim benzene.
Leej twg nrhiav tau C6H6?
Michael Faraday, tus kws tshawb fawb Askiv thawj zaug pom Benzene hauv cov roj teeb pom kev zoo. Lub npe benzene tau muab los ntawm German Chemist Mitscherich hauv xyoo 1833. Cov qauv cyclic ntawm benzene tseem yog qhov tsis paub txog mus txog rau xyoo 1865 thaum tus xibfwb German Lub Yim Hli Kekule piav qhia nws thaum nws npau suav txog tus nab tom nws tus Tsov tus tw.
Kekule tau npaj cov qauv ntawm benzene li cas?
Nyob rau xyoo 1865, Kekule tau qhia lub nplhaib qauv rau benzene uas muaj cov qauv cyclic planar qauv ntawm rau cov pa roj carbon monoxide muaj alternate ob thiab ib daim ntawv cog lusTxhua ntawm rau carbons tau txuas rau ib qho hydrogen. … (i) Benzene muaj peb ob daim ntawv cog lus. (ii) Tag nrho cov carbon thiab hydrogen atoms hauv benzene yog sib npaug.
benzene yog dab tsi thiab nws cov txiaj ntsig?
Benzene's molecular mis, C6H6, qhia txog qib siab ntawm unsaturation. … Thaum benzene reacts, nws ua li ntawd los ntawm kev hloov nyob rau hauv uas hydrogen atom hloov los ntawm lwm atom los yog ib pawg ntawm atoms. Lub sij hawm aromaticyog thawj zaug siv los faib cov benzene thiab nws cov derivatives vim tias ntau ntawm lawv muaj cov ntxhiab tsw txawv.
