Txheeb xyuas stereoisomers los ntawm lawv kev npaj hauv qhov chaw; cov tebchaw yuav muaj tib lub atoms thiab cov qauv kev sib txuas, tab sis yuav tau teem caij sib txawv hauv qhov chaw peb sab. Geometric isomers yeej yog ib hom configurational stereoisomer.
Tsis tas li ntawd, koj yuav txheeb xyuas tus isomer li cas?
Kev cai lij choj isomers yog cov tebchaw uas muaj tib cov qauv molecular thiab sib txuas sib txawv. Rau txiav txim seb ob lub molecules yog kev cai lij choj isomers , tsuas yog suav tus naj npawb ntawm txhua lub atom hauv ob qho tib si molecules thiab saib seb cov atoms tau npaj li cas.
Kuj Paub, 3 hom isomers yog dab tsi? Muaj peb hom ntawm tus qauv isomers : sawb isomers , pab pawg ua haujlwm isomers thiab positional isomers . Cov saw isomers muaj tib cov qauv molecular tab sis txawv kev npaj los yog ceg. Pab pawg ua haujlwm isomers muaj cov mis tib yam tab sis txawv pab pawg ua haujlwm.
Ib yam li ntawd ib tug yuav nug, dab tsi yog tus qauv ntawm isomers?
Cov qauv lossis kev cai lij choj Isomers Nrog cov qauv qauv C4H10 muaj ob qhov sib txawv isomers ua tau. Raws li tus naj npawb ntawm Carbons nyob rau hauv ib qho alkane nce, tus naj npawb ntawm cov qauv isomers kuj nce.
Yuav ua li cas koj txheeb xyuas tus isomer hauv organic chemistry?
Hauv organic chemistry , isomers yog cov molecules nrog tib cov qauv molecular (piv txwv li tib tus naj npawb ntawm cov atoms ntawm txhua lub caij), tab sis txawv structural los yog spatial kev npaj ntawm cov atoms nyob rau hauv lub molecule.

Koj qhia li cas yog tias daim duab yog qhov muaj nuj nqis tiag tiag?
Ib qho kev ua haujlwm zoo yuav yog xoom ntawm tus nqi tshwj xeeb ntawm x tsuas yog tias tus lej yog xoom ntawm qhov x thiab tus lej tsis yog xoom ntawm x. Hauv lwm lo lus, txhawm rau txiav txim siab seb qhov kev ua haujlwm muaj txiaj ntsig puas yog xoom txhua yam uas peb yuav tsum ua yog teeb tsa tus lej sib npaug rau xoom thiab daws
Koj tuaj yeem ua li cas yog tias koj tsis paub tias txheej twg yog nyob rau hauv cov txheej txheem rho tawm?
Koj tuaj yeem ua li cas yog tias koj tsis paub tias txheej twg yog nyob rau hauv cov txheej txheem rho tawm? Tso dej me me rau hauv lub caj dab ntawm qhov sib cais funnel. Ua tib zoo saib nws: yog tias nws tseem nyob hauv txheej txheej sab saud, txheej txheej ntawd yog txheej dej
Tam sim ntawd yuav siv dab tsi yog tias koj cov khaub ncaws raug hluav taws lossis yog tias muaj tshuaj lom loj tshwm sim ntawm koj cov khaub ncaws?
Tam sim ntawd yuav siv dab tsi yog tias koj cov khaub ncaws raug hluav taws lossis yog tias muaj tshuaj lom ntau tshwm sim ntawm koj cov khaub ncaws? Koj mus ncaj qha rau da dej kev nyab xeeb thiab sawb ntawm tag nrho koj cov khaub ncaws
Yuav ua li cas koj qhia yog hais tias muaj nuj nqi converges los yog diverges?
Yog hais tias koj tau txais ib tug series uas me dua ib tug convergent benchmark series, ces koj series yuav tsum converge. Yog hais tias lub benchmark converges, koj series converges; thiab yog hais tias tus benchmark diverges, koj series diverges. Thiab yog tias koj cov koob muaj ntau dua li qhov sib txawv ntawm qhov sib txawv, ces koj cov koob yuav tsum sib txawv
Yuav ua li cas koj qhia yog hais tias ib tug piecewise graph yog ib tug muaj nuj nqi?
Yuav Qhia Li Cas Yog Piecewise Function yog Nruam lossis Tsis Txuas Ntxiv. Txhawm rau qhia yog tias daim duab sib txuas tsis tu ncua lossis tsis txuas ntxiv, koj tuaj yeem saib cov ntsiab lus ciam teb thiab pom tias y point yog tib yam ntawm lawv txhua tus.(Yog tias y's txawv, yuav muaj "dhia" hauv daim duab !)
