POLAR THIAB NONPOLAR COMPOUNDS
Bonds uas yog ib feem ionic hu ua polar covalent bonds . Tsis muaj polar covalent bonds , nrog sib npaug sib faib ntawm daim ntawv cog lus electrons, tshwm sim thaum lub 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.
Hais txog qhov no, dab tsi txiav txim siab yog tias daim ntawv cog lus yog polar?
( Yog qhov txawv ntawm electronegativity rau cov atoms hauv a daim ntawv cog lus yog ntau dua 0.4, peb xav txog qhov daim ntawv cog lus polar . Yog qhov sib txawv ntawm electronegativity tsawg dua 0.4, lub daim ntawv cog lus yog qhov tseem ceeb tsis muaj polar.) Yog tsis muaj polar bonds , lub molecule yog nonpolar. Yog cov molecule muaj polar bonds , txav mus rau Kauj Ruam 3.
Tom qab ntawd, lo lus nug yog, KF puas yog daim ntawv cog lus cog lus? Polar covalent bonds . Tsuas yog homonuclear daim ntawv cog lus yog tiag tiag covalent , thiab yuav luag zoo meej ionic daim ntawv cog lus tuaj yeem tsim ntawm pawg I thiab pawg VII cov ntsiab lus, piv txwv li, KF.
Kuj paub, dab tsi yog polar thiab nonpolar bond?
Tsis muaj polar covalent daim ntawv cog lus yog ib hom tshuaj daim ntawv cog lus qhov twg ob atoms sib koom ib khub ntawm electrons rau ib leeg. Polar covalent kev sib raug zoo yog ib hom tshuaj daim ntawv cog lus qhov twg ib khub ntawm electrons tsis sib npaug ntawm ob lub atoms.
Cov ntawv cog lus twg muaj ntau dua polar?
Qhov sib koom electrons ntawm covalent daim ntawv cog lus tuav ntau nruj ntawm lub ntau electronegative element tsim ib feem tsis zoo nqi, thaum lub caij electronegative tsawg muaj ib feem zoo xwb,. Qhov loj dua qhov sib txawv ntawm electronegativity ntawm ob lub atoms, lub ntau polar tus daim ntawv cog lus.

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 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
Puas yog hypochlorous acid polar lossis nonpolar?
Hypochlorous acid yog HOCl. Ntawm no Oxygen atom yog sp3 hybridised. Yog li ntawd, nws tau khoov zoo ib ncig ntawm oxygen vim muaj ob leeg ib leeg. Qhov no ua rau net Dipole lub sij hawm (0.37 D) thiab yog li nws yog ib tug polar molecule
