Cov thawj kauj ruam yog los tshuaj xyuas qee qhov kev cai yooj yim thiab tom qab ntawd ua haujlwm los ntawm cov pab pawg ua haujlwm, maj mam tsim cov kev txawj uas yuav tsum tau ua.

Ib yam li ntawd, koj ua li cas Iupac nomenclature?

IUPAC Cov Cai rau Alkane Nomenclature

  1. Nrhiav thiab npe cov kab txuas txuas txuas ntev tshaj plaws.
  2. Txheeb xyuas thiab npe cov pab pawg uas txuas nrog cov saw no.
  3. Tus lej ntawm cov saw sib txuas ua ke, pib ntawm qhov kawg ze tshaj ib pab pawg hloov pauv.
  4. Tsim qhov chaw ntawm txhua pab pawg neeg hloov pauv los ntawm tus lej tsim nyog thiab lub npe.

Tsis tas li ntawd, dab tsi yog qhov tseem ceeb nomenclature? Cov pab pawg ua haujlwm nrog lub siab tshaj plaws qhov tseem ceeb 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 molecule yuav yog "-oic acid", tsis yog "-ib", vim tias carboxylic acids tau muab siab dua. qhov tseem ceeb.

Tom qab ntawd, lo lus nug yog, ua li cas koj lub npe organic tebchaw kauj ruam yog kauj ruam?

Compound naming kauj ruam

  1. Kauj Ruam 1: Nrhiav qhov ntev tshaj plaws carbon saw nyob rau hauv peb lub compound. Peb yuav siv qhov sib xyaw no ua peb tus piv txwv rau npe.
  2. Kauj Ruam 2: Lub npe uas ntev tshaj plaws carbon saw.
  3. Kauj Ruam 3: Txheeb xyuas qhov xaus (suffix) yuav tsum yog dab tsi.
  4. Kauj Ruam 4: Sau koj cov carbon atoms.
  5. Kauj Ruam 5: Sau npe cov pab pawg sab.

Lub nplhaib 5 carbon hu ua dab tsi?

Feem ntau nplhaib compounds muaj xws li 5 lub 6 carbon. Cov tebchaw no kuj yog hu ua cyclic. Cyclopentane: Txawm hais tias qhov kev sawv cev yooj yim tshaj plaws yog cov kab kos ntawm lub pentagon raws li qhia rau sab laug.
