Qhov sib txawv tseem ceeb ntawm cis cyclohexane thiab trans cyclohexane yog tias cis cyclohexane muaj nws cov neeg hloov pauv taw tes rau tib lub dav hlau ntawm lub nplhaib whereas trans cyclohexane muaj nws cov khoom siv taw qhia rau cov dav hlau sib txawv.
Cyclohexane yog cycloalkane nyob rau hauv uas muaj rau-tus tswvcuab lub nplhaib uas muaj nyob rau hauv lub rooj zaum conformation. Nyob rau hauv lub rooj zaum conformation, qhov sib xyaw no muaj lub kaum sab xis qis tshaj plaws; yog li, nws yog ruaj khov dua li lwm yam kev ua tau zoo. Ntxiv mus, nyob rau hauv no conformation, ib nrab ntawm cov hydrogen atoms txuas nrog carbon atoms nyob rau hauv lub dav hlau ntawm lub nplhaib. Peb hu qhov no ua equatorial positioning. Lwm ib nrab yog nyob perpendicular rau lub dav hlau ntawm lub nplhaib. Peb hu qhov no axial positioning. Thaum muaj ob lossis ntau qhov hloov pauv hauv cyclohexane, peb tuaj yeem soj ntsuam cis thiab trans isomerism los ntawm kev soj ntsuam seb cov neeg hloov pauv puas nyob hauv txoj haujlwm equatorial lossis txoj haujlwm axial.
Cis Cyclohexane yog dab tsi?
Cis cyclohexane yog geometric isomer ntawm cov organic compound cyclohexane. Lub cyclohexane molecule yuav tsum muaj ob (lossis ntau dua) hloov pauv kom pom qhov isomerism. Yog tias ob pawg neeg hloov pauv nyob hauv tib lub dav hlau (xws li equatorial lossis axial), ces peb hu nws lub cis isomer ntawm cyclohexane.
Daim duab 01: Cis thiab trans 1 methyl 4 hydroxymethyl cyclohexane
Piv txwv li, yog tias cyclohexane muaj methyl pawg (-CH3) thiab hydroxyl pawg (-OH) nyob rau hauv lub dav hlau axial, ces peb hu nws cis-1-methyl-4-hydroxymethyl cyclohexane. Cov qauv ntawm no isomer thiab qhov opposite (trans-isomer) yog muab nyob rau hauv daim duab saum toj no.
Dab tsi yog Trans Cyclohexane?
Trans cyclohexane yog geometric isomer ntawm cyclohexane uas muaj nws cov neeg hloov pauv hauv cov dav hlau rov qab. Qhov ntawd txhais tau tias; Yog hais tias ib tug hloov nyob rau hauv lub equatorial dav hlau, lwm yam substituent yuav nyob rau hauv lub axial dav hlau thiab vice versa. Hauv qhov piv txwv saum toj no (hauv isomers ntawm 1 methyl 4 hydroxymethyl cyclohexane), cov qauv trans muaj methyl pawg hauv lub dav hlau equatorial thaum pawg hydroxyl nyob hauv lub dav hlau axial.
Qhov txawv ntawm Cis thiab Trans Cyclohexane yog dab tsi?
Cyclohexane yog cov organic compound uas muaj rau cov pa roj carbon atom txuas rau ib leeg ntawm ib qho kev sib cog lus, tsim ib lub nplhaib rau 6 tus tswv cuab. Nws tuaj yeem pom cis-trans isomerism. Qhov sib txawv tseem ceeb ntawm cis cyclohexane thiab trans cyclohexane yog tias cis cyclohexane muaj nws cov khoom siv taw qhia rau tib lub dav hlau ntawm lub nplhaib whereas trans cyclohexane muaj nws cov khoom siv taw qhia rau cov dav hlau sib txawv. Qhov ntawd txhais tau tias; Yog hais tias cov neeg hloov pauv nyob rau hauv lub dav hlau equatorial (los yog nyob rau hauv lub dav hlau axial), nws yog ib tug cis isomer thaum lub substituents nyob rau hauv opposite dav hlau (ib tug hloov nyob rau hauv lub equatorial dav hlau thiab lwm yam nyob rau hauv axial dav hlau), ces lub isomer yog trans.
Summary – Cis vs Trans Cyclohexane
Cyclohexane yog ib qho organic compound uas tuaj yeem qhia cis-trans isomerism thaum nws muaj ob lossis ntau qhov hloov pauv. Qhov sib txawv tseem ceeb ntawm cis cyclohexane thiab trans cyclohexane yog tias cis cyclohexane muaj nws cov neeg hloov pauv taw qhia rau tib lub ntsej muag ntawm lub nplhaib whereas trans cyclohexane muaj nws cov neeg hloov pauv taw qhia rau lub ntsej muag.
