Muab lub npe IUPAC rau cov ntsiab lus hauv qab no:

  1. Txheeb xyuas pawg ua haujlwm.
  2. Nrhiav qhov ntev tshaj plaws carbon chain muaj cov functionalgroup.
  3. Sau cov carbons nyob rau hauv cov saw ntev tshaj plaws.
  4. Nrhiav txhua pab pawg, npe lawv thiab muab tus lej ntawd carbon atom uas pab pawg isattached.

Cov lus nug tseem yog, koj ua li cas lub npe Iupac organic compound?

IUPAC Cov cai. Nyob rau hauv thiaj li yuav npe organic compounds koj yuav tsum xub cim ob peb yam yooj yim npe . Cov no npe tau teev nyob rau hauv kev sib tham ntawm npe alkanes. Feem ntau, lub hauv paus ib feem ntawm lub npe qhia txog tus naj npawb ntawm carbons nyob rau hauv dab tsi koj tau muab los ua tus niam txiv saw.

Ib yam li ntawd, pawg haujlwm twg muaj qhov tseem ceeb tshaj plaws? Cov ua haujlwm pab pawg nrog tus qhov tseem ceeb tshaj plaws yuav yog tus uas muab nws lub ntsiab lus rau lub npe ntawm lub molecule. Yog li hauv qhov piv txwv # 1 saum toj no, cov lus kawg ntawm cov moleculew yuav yog "-oic acid", tsis yog "-ib", vim tias carboxylic acids tau muab. qhov tseem ceeb dua.

Ua li no, ua li cas koj lub npe organic tebchaw?

Cov kev cai no tau nyuaj, tab sis peb tau sim ua kom yooj yim siv 6 kauj ruam:

  1. Nrhiav qhov ntev tshaj plaws carbon saw nyob rau hauv peb lub compound.
  2. Lub npe uas niam txiv saw (nrhiav lo lus hauv paus)
  3. Xav txog qhov kawg.
  4. Sau koj cov pa roj carbon atom.
  5. Sau npe cov pab pawg sab.
  6. Muab cov pab pawg nyob rau hauv cov ntawv sau.

Dab tsi ua rau cov organic compound?

Organic compound , ib qho ntawm cov chav kawm loj ntawm cov tshuaj tshuaj sib xyaw nyob rau hauv uas ib los yog ntau lub atoms ntawm carbon yog covalently txuas rau atoms ntawm lwm yam, feem ntau hydrogen, oxygen, los yog nitrogen. Ob peb cov pa roj carbon tshuaj sib xyaw tsis cais raws li organic muaj xws li carbide, carbonates, thiab cyanides.
