Lawv daim ntawv cog lus dipoles tsis tso tseg, yog li cov molecule yog polar . Ntawm qhov tod tes, XeF4 muaj ob leeg ib leeg ntawm Xe. Qhov no yog tus lej sib npaug, yog li koj yuav tsum kuaj xyuas qhov zoo ntawm cov molecule. Ntawm no, Xe-F daim ntawv cog lus dipoles tshem tawm ib leeg, yog li cov molecule yog tsis muaj polar.
Xav txog qhov no, yog SbF5 polar lossis nonpolar?
SbF5 tsim cov duab trigonal bipyramidal. Muaj polar daim ntawv cog lus tam sim no thiab kuv xav tias nws yog tsis polar vim nws yog molecular geometry. Txawm li cas los xij, Lub molecule nws tus kheej tsis yog symmetrical nkaus (tshwj tsis yog kuv xav txog symmetry tsis raug).
Kuj Paub, puas yog sf5 muaj lub sijhawm dipole? Txawm hais tias lub molecule zoo li CHCl 3 yog qhov zoo tshaj plaws piav raws li tetrahedral, cov atoms khi rau carbon tsis zoo ib yam. Yog li ntawd, daim ntawv cog lus dipole moments tsis tuaj yeem tso tseg ib leeg, thiab cov molecule muaj lub sijhawm dipole.
Tom qab ntawd, lo lus nug yog, koj yuav qhia li cas tias nws yog polar lossis nonpolar?
Kauj ruam 2: Txheeb xyuas txhua daim ntawv cog lus raws li ib yam polar los yog nonpolar . ( Yog Qhov sib txawv ntawm electronegativity rau cov atoms hauv ib daim ntawv cog lus yog ntau dua 0.4, peb xav txog cov nyiaj polar . Yog qhov sib txawv ntawm electronegativity yog tsawg dua 0.4, daim ntawv cog lus yog qhov tseem ceeb tsis muaj polar .) Yog tsis muaj polar bonds, lub molecule yog tsis muaj polar.
Dab tsi yog qhov molecular geometry ntawm sf5 -?
SF6 yog octahedral puab uas ua rau kev nkag siab zoo tag nrho. SF5 + npaj 5 khub ntawm electrons hauv trigonal bipyramidal qauv.

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 bonds polar lossis nonpolar?
POLAR THIAB NONPOLAR COMPOUNDS Bonds uas yog ib feem ionic hu ua polar covalent bonds. Nonpolar covalent bonds, nrog sib npaug sib npaug ntawm daim ntawv cog lus electrons, tshwm sim thaum electronegativities ntawm ob lub atoms sib npaug. Qhov tshwm sim yog ib daim ntawv cog lus uas tus khub electron hloov mus rau ntau lub atom electronegative
Puas yog Cl Cl polar lossis nonpolar?
Thaum qhov sib txawv me me los yog xoom, daim ntawv cog lus yog covalent thiab nonpolar. Thaum nws loj, daim ntawv cog lus yog polar covalent lossis ionic. Qhov tseem ceeb ntawm qhov sib txawv ntawm electronegativity ntawm cov atoms hauv daim ntawv cog lus H-H, H-Cl, thiab Na-Cl yog 0 (nonpolar), 0.9 (polar covalent), thiab 2.1 (ionic), feem
Puas yog SeCl4 polar lossis nonpolar?
Yog lawm. Lub SeCl4 molecule yog polar vim hais tias ib leeg khub ntawm nonbonding electrons nyob rau hauv lub valence plhaub ntawm lub selenium atom interacts nrog lub bonding khub ntawm electrons, ua rau ib tug spatial asymmetry ntawm lub dipole lub sij hawm ntawm lub polar Se-Cl bonds. Qhov tshwm sim yog SeCl4 molecule nrog lub sijhawm net dipole
Puas yog c3h8 polar lossis nonpolar?
Carbon thiab hydrogen muaj ze rau tib lub electronegativity, lub zog ntawm attraction ntawm ib tug electron rau ib tug atom. Nws ua raws li hais tias ib qho hluav taws xob sib koom ntawm lawv yog sib npaug rau ob qho tib si. Qhov no tiv thaiv lub sijhawm dipole los ntawm kev tsim, wherece propane (C3H8) yog nonpolar
