Peb paub tias polar molecules yog nyiam rau ib leeg los ntawm dipole-dipole attractions ntawm ib feem tsis zoo nqi ntawm ib tug polar molecule thiab tus nqi zoo ib nrab rau lwm polar molecule.
Tom qab ntawd, ib tug kuj nug, puas polar thiab nonpolar molecules nyiam?
Polar cov ntaub ntawv zoo li yuav ntau dua nyiam mus thiab muaj ntau soluble nyob rau hauv polar cov kuab tshuaj. Tsis muaj polar cov ntaub ntawv zoo li yuav nyiam mus thiab muaj ntau soluble nyob rau hauv tsis muaj polar cov ntaub ntawv. Polar molecules yog cov uas muaj thaj tsam ntawm qhov zoo thiab qhov tsis zoo. Dej yog ib qho piv txwv ntawm a polar khoom.
Kuj Paub, ib qho molecule puas tuaj yeem yog ob qho tib si polar thiab nonpolar? A molecule tau muaj polar bonds thiab tseem yuav tsis muaj polar . Yog tias polar daim ntawv cog lus sib npaug (lossis symmetrically) faib, daim ntawv cog lus dipoles tshem tawm thiab tsis tsim ib qho molecular dipole.
Ib yam li ntawd, yog vim li cas cov molecules nonpolar attracted rau ib leeg?
Nyob rau hauv cov ntaub ntawv ntawm tsis-polar molecules , dispersion rog lossis London rog muaj nyob nruab nrab ntawm lawv. Cov zog no yog induced dipole - induced dipole kev sib tshuam. Qhov tsis zoo (electrons) ntawm ib qho molecule nyiam qhov zoo (nucleus) ntawm lwm molecule . Yog li ntawd, ob lub dipoles yog induced.
Puas yog dej polar lossis nonpolar?
Dej (H2O) yog polar vim qhov khoov zoo ntawm cov molecule. Cov duab txhais tau hais tias feem ntau ntawm cov nqi tsis zoo los ntawm cov pa oxygen ntawm sab ntawm lub molecule thiab cov nqi zoo ntawm hydrogen atoms nyob rau sab nraud ntawm lub molecule. Qhov no yog ib qho piv txwv ntawm polar covalent chemical bonding.

Polar molecules puas tiv thaiv cov tsis muaj polar molecules?
Polar molecules (nrog +/- tsub) yog nyiam rau cov dej molecules thiab yog hydrophilic. Nonpolar molecules yog repelled los ntawm dej thiab tsis yaj hauv dej; yog hydrophobic
Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
Puas yog dej molecules nyiam rau lwm cov polar molecules?
Raws li qhov tshwm sim ntawm dej polarity, txhua tus dej molecule attracts lwm cov dej molecules vim yog cov nqi sib txawv ntawm lawv, tsim hydrogen bonds. Dej kuj nyiam, lossis nyiam, lwm cov polar molecules thiab ions, suav nrog ntau cov biomolecules, xws li qab zib, nucleic acids, thiab qee cov amino acids
Dab tsi yog lub zog txaus nyiam ntawm ob lub cev ntawm cov khoom sib txawv uas sib cuag nrog ib leeg?
Biology Tshooj 3 Lub Vocabulary A B Polar Molecules nrog ib nrab nqi ntawm qhov xaus. Cov dej molecule muaj cov khoom no. Cohesion Lub zog uas tuav cov molecules ntawm ib qho khoom ua ke. Adhesion Lub zog txaus nyiam ntawm ob lub cev ntawm cov khoom sib txawv uas sib cuag nrog ib leeg
Dab tsi yog qhov sib txawv ntawm qhov sib txawv ntawm cov kab sib txuas thiab ntau qhov sib piv?
6. (2 lub cim) Qhov sib txawv ntawm cov kab sib txuas (kev sib piv) thiab ntau qhov sib piv yog dab tsi? Cov kab sib xyaw ua ke yog npaj sib piv; uas yog, tshwj xeeb txhais tau tias yog ua ke nyob rau hauv ntau txoj kev thiab contrasted nrog rau lwm yam kev sib txuas ntawm txhais tau tias
