Video: Yuav ua li cas koj tig lub rooj zaum conformation?
2024 Tus sau: Miles Stephen | [email protected]. Kawg hloov kho: 2023-12-15 23:36
- Ob tug Chair Conformations Ntawm 1-Methyl Cyclhexane .
- Ua li no Conformations Hloov pauv?
- Kauj ruam 1: Nqa ib qho "Footrest" ntawm Cov Lub rooj zaum Ua A” Nkoj ”Hmoob.
- Kauj Ruam 2: Rub Lub Taub Hau Tawm Sab Nraud So Kom Ua Ib Lub Khaub Ncaws Tshiab.
- Cov Lub rooj zaum Flip Hloov Txhua pawg Axial rau Equatorial Ones, Thiab Vice Versa.
Ib yam li ntawd, koj ua li cas ua lub rooj zaum conformation nplhaib flip?
Kos lub rooj zaum Conformations thiab Nplhaib Flips rau Cyclohexane
- Nov yog kuv txoj hauv kev:
- Kos 2 kab sib luag me ntsis offset ntawm ib leeg.
- Muab ib qho chaw tso rau saum qhov qhib sab saud, thiab lwm qhov hauv qab qhov qhib qis.
- Txuas cov dots.
- Txheeb xyuas qhov 'up tip' OR 'down tip' ntawm koj lub rooj zaum conformation, thiab kos ib txoj kab ncaj nraim (up tip) los yog down (down tip) parallel to the y-plane.
Qhov thib ob, yog lub nplhaib flips enantiomers? (Daim iav duab kev sib raug zoo tuaj yeem pom los ntawm kev sib piv cov " nplhaib flip "conformation of the Chair Projection on the right to the current conformation of the Chair Projection nyob rau sab laug. Rau kev qhia txog yuav ua li cas ua ib tug " nplhaib flip , " nyem qhov no.) Yog li ntawd, cov molecules yog cov enantiomers.
Tsis tas li ntawd, dab tsi ua rau lub rooj zaum conformation ruaj khov?
Yog vim li cas yog tias thaum hloov pauv nyob rau hauv txoj hauj lwm axial, muaj feem yuav ntau kev cuam tshuam tsis zoo nrog lwm cov axial atoms ntawm tib sab. Thaum cov neeg hloov pauv nyob hauv txoj haujlwm equatorial, lawv nyob deb ntawm ib leeg. Qhov no nce lub ruaj khov ntawm kev sib haum xeeb.
Lub nplhaib flip yog dab tsi?
Hauv organic chemistry, a nplhaib flip (tseem hu ua a nplhaib inversion los yog nplhaib reversal) yog kev sib hloov ntawm cyclic conformers uas muaj qhov sib npaug nplhaib cov duab (piv txwv li, los ntawm lub rooj zaum conformer mus rau lwm lub rooj zaum conformer) uas ua rau muaj kev sib pauv ntawm cov haujlwm tsis sib xws.

Dab tsi yog lub ntsiab lus 11 ntawm lub rooj zaum?
Sodium yog lub ntsiab lus uas yog atomic naj npawb 11 ntawm lub sijhawm teem sijhawm
Puas yog lub rooj zaum tig yog enantiomer?
(Daim iav duab kev sib raug zoo tuaj yeem pom los ntawm kev sib piv 'ntiv nplhaib flip' conformation ntawm lub rooj zaum Projection ntawm sab xis mus rau qhov tam sim no conformation ntawm lub rooj zaum Projection nyob rau sab laug. Rau kev qhia txog yuav ua li cas ua ib tug 'ring flip,' nyem qhov no. Yog li ntawd, cov molecules no yog enantiomers
Yuav ua li cas koj nco lub sij hawm lub rooj song?
VIDEO Tsuas yog li ntawd, koj yuav ua li cas thiaj nco tau thawj 20 lub ntsiab lus ntawm lub sijhawm? Mnemonic Device: Zoo siab Henry Nyob Ib sab ntawm Boron Tsev, Nyob ze Peb tus phooj ywg Nelly Nancy MgAllen. Silly Patrick nyob ze. Arthur Kisses Carrie.
Yuav ua li cas koj nyeem ib lub rooj zaum Square?
Txhua square ntawm lub sij hawm muab cov ntaub ntawv tshwj xeeb txog cov atoms ntawm lub caij. Tus lej nyob rau sab saum toj ntawm lub square yog tus naj npawb atomic, uas yog tus naj npawb ntawm protons nyob rau hauv lub nucleus ntawm lub atom ntawm lub caij. Cov cim tshuaj lom neeg yog ib qho luv luv rau lub caij lub npe. Nws muaj ib lossis ob tsab ntawv
Koj puas nco qab cov ntsiab lus D block ntawm lub rooj zaum?
D-block ntsiab nws suav nrog Lutetium (Lu), Hafnium (Hf), Tantalum (Ta), Tungsten (W), Rhenium (Re), Osmium (Os), Iridium (Ir), Platinum (Pt), Kub (Au thiab Mercury (Hg). Mnemonic for Period 6: L(u)a HafTa Warna Reh Us(Os) Irritating Popat ke saath Aur Hoj(g)a pagal
