Lub npe Cycloalkanes

Siv cov cycloalkane raws li niam txiv saw yog tias nws muaj cov pa roj carbon ntau dua li lwm cov khoom siv alkyl. b Yog hais tias ib qho alkyl saw tawm ntawm cycloalkane muaj cov pa roj carbon ntau dua, ces siv cov saw hlau alkyl ua niam txiv thiab cov cycloalkane raws li cycloalkyl- hloov pauv.

Ntxiv mus, ua li cas koj lub npe alkanes thiab cycloalkanes?

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.

Ib tug kuj nug, ua li cas koj lub npe cyclic molecules? A cyclic (ntiv nplhaib) hydrocarbon yog tsim los ntawm cov lus ua ntej cyclo- uas tshwm ncaj qha rau pem hauv ntej ntawm lub hauv paus npe . Hauv cov ntsiab lus, cov npe ntawm lub compound yog sau tawm nrog cov substituents nyob rau hauv alphabetical kev txiav txim raws li los ntawm lub hauv paus npe (muab los ntawm tus naj npawb ntawm carbons nyob rau hauv niam txiv saw).

Hauv qhov no, Cycloalkanes muab piv txwv li cas?

Qee qhov sib txawv piv txwv ntawm cycloalkanes yog cov cyclopentane, Cyclobutane, cyclohexane, thiab cycloheptane, cyclooctane, thiab lwm yam raws li qhia hauv qab no hauv daim duab. Tus naj npawb ntawm carbon atoms tam sim no nyob rau hauv lub compound txiav txim tus qauv ntawm cycloalkane.

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 yooj yim tshaj plaws sawv cev yog hais tias ntawm ib kab kos ntawm ib tug pentagon raws li qhia nyob rau sab laug.
