Alkanes . Ib alkane yog ib qho hydrocarbon uas tsuas muaj ib qho kev sib cog lus xwb. Cov simplestalkane yog methane, nrog rau cov mis molecular CH4. Cov pa roj carbonis lub hauv paus atom thiab ua rau plaub ib qho kev sib cog lus rau hydrogen atoms.
Yog li ntawd, dab tsi yog ib tug ncaj saw alkane?
Ib alkane yog ib qho hydrocarbon uas tsuas muaj ib qho kev sib cog lus xwb. Cov no alkanes hu ua ncaj - chain alkanes vim tias cov pa roj carbon atoms txuas rau hauv ib qho txuas ntxiv saw hlau tsis muaj ceg. Namingand sau cov qauv thiab cov qauv molecular rau cov ncaj - chain alkanes yog ncaj nraim.
Kuj Paub, ua li cas koj lub npe ncaj saw alkane? Cov kauj ruam rau Naming Straight Chain Alkanes
- Lub npe ntawm alkane yog ua los ntawm ob ntu:
- Lub npe ntawm ib tug ncaj saw alkane ib txwm xaus nyob rau hauv lub suffixane.
- Thawj feem ntawm lub npe ntawm cov saw ncaj alkane, nws ua ntej lossis qia, yog txiav txim siab los ntawm tus lej ntawm cov atoms hauv cov saw:
Tib neeg kuj nug tias, txoj saw ncaj yog dab tsi?
Kev txhais ntawm ncaj saw .: ib open saw hlau ntawm atoms tsis muaj sab chains -feem ntau hyphenated thaum siv attributively.
Dab tsi yog cov saw ncaj hydrocarbons?
Tsis yog tag nrho hydrocarbons yog ncaj chains . Ntau hydrocarbons muaj ceg ntawm C atoms txuas rau a saw hlau ; lawv hu ua ceg hydrocarbons . Cov kab mob alkanes no yog isomers ntawm ncaj - saw hlau alkanes muaj tib tus lej ntawm C atoms.
