1, 2- Cov tshuaj dichloroethene Piv txwv li: Ob leeg ntawm isomers muaj raws nraim tib lub atoms koom nyob rau hauv raws nraim tib yam kev txiav txim. Qhov txawv ntawm ob yog qhov cis isomer yog a polar molecule thaum lub trans isomer tsis yog- polar.
Tsis tas li ntawd, yog c2cl2h2 polar?
Lus Nug: Rau C2H2Cl2 , yog teem nrog ob H ntawm ib sab thiab ob Cl ntawm ib leeg (hauv cis kev npaj), nws ua rau ib qho polar molecule.
Ib yam li ntawd, yog C2H4Cl2 polar lossis nonpolar? e.g. C2H4Cl2 : Cov molecule ntawm sab laug zoo li muaj C-Cl dipoles hauv txoj haujlwm tshem tawm yog li yuav tsis muaj net dipole , tab sis cov molecule rotates nyob ib ncig ntawm C-C daim ntawv cog lus kom tsuas yog rau lub sij hawm luv luv lawv tshem tawm. Ntawm tag nrho lwm yam kev teeb tsa, ob lub dipoles ntxiv rau lub vas dipole , yog li no yog a polar molecule.
Ntawm no, yog ch2ccl2 polar?
Cov ntawv cog lus tus kheej hauv dichloromethane yog qee yam polar vim qhov sib txawv ntawm electronegativity ntawm C & H thiab ntawm C & Cl, yog li yog, nws yog polar ntawm daim ntawv cog lus. Txawm li cas los xij, net polarity yog me me, kom lub molecule yog NW nyuam qhuav polar.
Yuav ua li cas lub molecule ua 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.

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
Puas yog SeO3 polar lossis nonpolar?
SeO3 thiab SeO2 ob qho tib si muaj polar bonds tab sis tsuas yog SeO2 muaj lub sijhawm dipole. Peb daim ntawv cog lus dipoles los ntawm peb lub ncov qaumteb qabteb Se-O daim ntawv cog lus hauv SeO3 yuav tag nrho tshem tawm thaum summed ua ke. Li no, SeO3 yog nonpolar vim tag nrho cov molecule tsis muaj lub sij hawm tshwm sim dipole
Puas yog ib qho tsis muaj polar molecule puas muaj hydrogen bonding?
Yog hais tias lub molecule tsis yog polar, ces tsis muaj kev sib cuam tshuam dipole-dipole los yog hydrogen bonding tuaj yeem tshwm sim thiab tsuas yog ua tau intermolecular quab yuam yog lub zog van der Waals tsis muaj zog
Puas yog acetonitrile polar lossis tsis polar?
Acetonitrile muaj 5.8 polarity index.Hydrocarbons tsis-polar yog li lawv yog cov kuab tshuaj tsuas yog rau lwm yam tshuaj tsis-polar. Tsis zoo li hydrocarbons, Ethyl Cawv muaj ob pawg polar thiab non-polarchemical ntawm cov molecule
Puas yog acetone yog polar aprotic hnyav?
Txawm li cas los xij, acetone tseem suav tias yog cov kuab tshuaj polaraprotic, txawm tias qhov tseeb tias nws yog acidic, thiab tsis muaj acidic tsawg dua li cawv. Tom qab ntawd dua, acetone (thiab lwm yam carbonyl uas muaj cov kuab tshuaj) yog, qhov tseeb, cov kuab tshuaj tsis zoo thaum siv cov hauv paus muaj zog vim lawv cov acidity siab
