Cov rooj zaum conformation yog qhov ruaj khov tshaj plaws conformation ntawm cyclohexane . Ib tug thib ob, ntau tsawg ruaj khov conformer yog nkoj conformation . Qhov no ib yam nkaus thiab yuav luag dawb ntawm lub kaum sab xis, tab sis nyob rau hauv sib piv muaj torsional strain txuam nrog eclipsed bonds ntawm plaub ntawm C atoms uas. daim ntawv sab ntawm lub nkoj.

Tsuas yog li ntawd, lub rooj zaum thiab lub nkoj conformation yog dab tsi?

Cov lub rooj zaum , nkoj , thiab twist- nkoj conformations qhia cov ces kaum kom ze rau qhov zoo tagnrho 109.5o, thiab cov no yog cov duab uas feem ntau cyclohexane molecules yeej pom muaj nyob rau hauv. kev sib haum xeeb uas cyclohexane tuaj yeem tsim. Lub zog qis tshaj plaws kev sib haum xeeb yog rooj zaum conformation ; yog li ntawd, nws yog qhov nrov tshaj plaws.

Ib yam li ntawd, vim li cas lub rooj zaum zoo dua rau daim ntawv nkoj? Cov rooj zaum conformation kev kos duab yog nyiam tshaj qhov nkoj vim yog lub zog, qhov steric hindrance, thiab ib hom tshiab hu ua transannular strain. Cov nkoj conformation tsis yog tus nyiam kev sib haum xeeb vim tias nws tsis ruaj khov thiab muaj qhov tsis txaus ntseeg ntawm ob lub H's, qhia nrog cov kab liab liab.

Ntawm no, vim li cas lub rooj zaum daim ntawv ntawm cyclohexane ruaj khov dua?

Lub rooj zaum conformation ntawm cyclohexane yog ruaj khov dua dua lub nkoj daim ntawv vim in lub rooj zaum Conformaion C-H bonds yog sib npaug axial thiab equatorial, piv txwv li, tawm ntawm kaum ob C-H bonds, rau yog axial thiab rau yog equatorial thiab txhua carbon muaj ib tug axial thiab ib tug equatorial C-H daim ntawv cog lus.

Dab tsi yog txhais los ntawm inversion ntawm lub rooj zaum conformation ntawm cyclohexane?

Lub rooj zaum - lub rooj zaum Kev sib hloov ntawm lub rooj zaum conformers yog hu ua nplhaib flipping los yog lub rooj zaum - tig. Carbon-hydrogen bonds uas yog axial nyob rau hauv ib tug configuration ua equatorial nyob rau hauv lwm yam, thiab vice versa. Hauv chav sov ob rooj zaum conformations nrawm sib npaug.
