Chiral molecules feem ntau muaj tsawg kawg yog ib qho carbon atom nrog plaub yam tsis muaj kev hloov pauv. Xws li ib carbon atom npe a chiral center (los yog tej zaum astereogenic center), siv organic-hais lus. Tej molecule uas muaj a chiral center yuav chiral (nrog rau qhov tshwj xeeb ntawm meso compound).

Tsis tas li cov lus nug yog, koj yuav ua li cas txheeb xyuas cov chiral carbon?

Chiral cov chaw yog tetrahedral atoms (feem ntau carbons ) uas muaj plaub qhov sib txawv. Txhua chiral Qhov nruab nrab hauv ib lub molecule yuav yog R lossis S. Raws li tau sau tseg, cov molecules nrog ib qho chiral center yog chiral . Molecules nrog ntau tshaj ib chiral feem ntau yog centerare chiral . Qhov tshwj xeeb yog cov khoom sib xyaw.

Tsis tas li ntawd, chiral carbon txhais li cas? A chiral carbon los yog asymmetric carbon atomis ib carbon atom uas txuas rau plaub hom ntawm atoms lossis pawg ntawm atoms.

Yog li ntawd, ua li cas koj thiaj paub yog tias ib yam dab tsi yog chiral?

Nrhiav cov pa roj carbon nrog plaub pawg sib txawv txuas nrog txheeb xyuas peev xwm chiral chaw. Kos koj cov molecule nrog wedges thiab dashes thiab tom qab ntawd kos ib daim iav duab ntawm lawv cov molecule. Yog Lub molecule nyob rau hauv daim iav duab yog tib yam molecule, nws yog achiral. Yog lawv yog txawv molecules, ces nws yog chiral.

Nws txhais li cas los ua chiral?

ˈræl?tiː/ yog ib qho cuab yeej ntawm asymmetry tseem ceeb nyob rau hauv ob peb ceg ntawm science. Lo lus chirality yog muab los ntawm Greekχειρ (kheir), "tes," ib tug paub chiral khoom. Ib yam khoom lossis qhov system yog chiral yog nws yog distinguishable los ntawm nws daim iav daim iav; uas yog , nws tsis tuaj yeem pom zoo rau nws.
