Cov qauv isomers muaj tib cov qauv molecular tab sis a txawv kev sib koom ua ke ntawm cov atoms. Stereoisomers muaj cov qauv molecular zoo tib yam thiab kev npaj ntawm atoms. Lawv txawv ntawm ib leeg xwb hauv spatial orientation ntawm pawg hauv molecule.

Qhov sib txawv, qhov txawv ntawm conformational thiab structural isomers yog dab tsi?

Kev cai lij choj isomers hu ua Cov txheej txheem isomers hauv tej phau ntawv. Stereoisomers: Ob lub molecules nrog tib txoj cai tab sis txawv stereochemistry. Conformational Isomers (Conformers): Ob lub molecules nrog tib lub teeb tab sis txawv conformation.

Tus qauv isomer zoo li cas? Cov qauv isomers yog molecules uas muaj tib cov qauv molecular tab sis nrog cov atoms txuas nrog rau qhov sib txawv. Nyob ntawd yog peb hom Cov txheej txheem isomers . Hauv saw isomers , carbon atoms yog txuas rau hauv kev txiav txim sib txawv. Hauv ib qho ntawm lawv, butane, cov pa roj carbon atoms pw hauv "txoj saw ncaj".

Xav txog qhov no, qhov txawv ntawm stereoisomers thiab kev cai lij choj isomers yog dab tsi?

Kev cai lij choj ( tus qauv ) isomers yog cov tebchaw nrog tib cov qauv molecular tab sis nrog a txawv qauv. Stereoisomers (spatial isomers ) yog cov tebchaw nrog tib cov qauv molecular thiab cov qauv ua haujlwm tab sis nrog a txawv spatial orientation ntawm cov molecules los yog lawv qhov chaw.

Dab tsi yog isomers piv txwv?

Butane thiab isobutane muaj tib cov pa roj carbon (C) atoms thiab hydrogen (H) atoms, yog li lawv cov qauv molecular yog tib yam. Txawm li cas los xij, txhua tus muaj cov qauv qauv sib txawv, uas qhia tau hais tias cov atoms tau npaj li cas. Yog li peb tuaj yeem hais tias butane thiab isobutane yog cov qauv isomers.
