Raws li nws txuas ntxiv tig, nws ntsib qhov tsis zoo eclipsed conformation uas ib pawg methyl eclipses hydrogen. Raws li kev sib hloov txuas ntxiv mus, cov molecule los mus rau kev tiv thaiv conformation, uas yog qhov ruaj khov tshaj plaws vim cov neeg hloov pauv tau staggered thiab cov methyl pawg nyob deb ntawm ib leeg li sai tau
Dab tsi ua rau kev sib haum xeeb ruaj khov?
Lub rooj zaum sib haum yog ruaj khov vim nws tsis muaj kev cuam tshuam tsis zoo lossis tsis muaj kev cuam tshuam ntawm cov ntawv cog lus hydrogen … Ntawm ob txoj haujlwm ntawm H's, daim ntawv sib npaug yuav yog qhov ruaj khov tshaj plaws vim tias cov hydrogen atoms, lossis tej zaum lwm qhov hloov pauv, yuav tsis kov ib leeg.
Puas yog tus tiv thaiv conformer ruaj khov tshaj?
Qhov kev sib haum xeeb tshaj plaws yog anti ntawm ob daim ntawv cog lus, whereas tsis ruaj khov conformations muaj gaache kev sib tshuam.
Kev sib haum xeeb twg yog qhov ruaj khov tshaj?
…nrog rau lwm tus-qhov kev ua raws li eclipsed yog qhov ruaj khov tshaj plaws, thiab kev sib haum xeebyog qhov ruaj khov tshaj plaws. Qhov kev hloov pauv uas tshwm sim tau hais tias raug kev nyuaj siab vim yog kev quab yuam ntawm cov hluav taws xob nyob hauv C -H daim ntawv cog lus ntawm cov carbons uas nyob ib sab.
Rau qhov twg ntawm cov hauv qab no sib xyaw gauche conformation yog qhov ruaj khov dua li nws qhov kev sib haum xeeb?
Anti conformation of NH2−CH2−CH2−NH2 yog ib txwm ruaj khov dua nws Gauche conformation.

Kev kwv yees siv tau los ua tiv thaiv mechanism nyob rau hauv txhua qhov xwm txheej. Tib neeg tiv thaiv lawv tus kheej los ntawm kev tsis lees paub cov yam ntxwv, kev xav, lossis kev xav uas lawv pom muaj kev hem thawj thaum pom cov yam ntxwv zoo ib yam ntawm lwm tus .
Yuav ua li cas tiv thaiv kev tiv thaiv los ntawm kev tshem tawm?
Sing react-router koj tuaj yeem tiv thaiv txoj kev hloov pauv tau yooj yim (uas yuav tiv thaiv kev tiv thaiv unmount) los ntawm kev siv Prompt. Koj yuav tsum tau manually hla tus getUserConfirmation prop uas yog ib qho haujlwm. Koj tuaj yeem hloov kho qhov haujlwm no raws li koj nyiam hauv txhua Router (Browser, Memory lossis Hash) los tsim koj cov lus pom zoo kev cai (piv txwv li .
Puas yog kev tiv thaiv lossis tiv thaiv?
verb (siv yam tsis muaj khoom), coped, cop·ingtawm tsam lossis cuam tshuam, tshwj xeeb tshaj yog cov ntsiab lus ncaj ncees lossis nrog qee qhov kev vam meej (feem ntau ua raws nrog): Cov cua sov thiab cua txias tshiab tuaj yeem tiv taus qhov kub thiab txias ntau dua li qhov qub.
