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 cov electronegativity sib txawv ntawm cov atoms nyob rau hauv lub daim ntawv cog lus H–H, H–Cl, thiab Na–Cl yog 0 (nonpolar), 0.9 (polar covalent), thiab 2.1 (ionic), feem.
Hauv qhov no, hom ntawv cog lus twg yog Cl Cl?
Lwm qhov piv txwv ntawm covalent daim ntawv cog lus yog cov Cl - Cl daim ntawv cog lus nyob rau hauv ib tug chlorine molecule. Ob lub chlorine atoms yog attracted rau tib khub ntawm electrons. Txhua chlorine atom muaj xya valence electrons nyob rau hauv peb lub zog theem thiab yuav tsum tau ib tug ntxiv electron rau daim ntawv ib tug electron tub ntxhais nrog ib tug argon electron configuration.
Tsis tas li ntawd, cl2 puas yog polar lossis nonpolar molecule? Piv txwv li, Cl2 molecule tsis muaj polar bonds vim hais tias tus nqi hluav taws xob zoo ib yam ntawm ob lub atoms. Nws yog li ntawd a tsis muaj polar molecule.
Ntxiv mus, yog P thiab CL polar lossis nonpolar?
1 Teb. Cov P -Cl daim ntawv cog lus ntau dua polar.
Vim li cas C CL polar?
Yog li ntawd, lub C -H daim ntawv cog lus tsis yog ib polar covalent bond. Nyob rau hauv sib piv, lub dipole lub sij hawm ntawm lub C - Cl bond nyob rau hauv molecules xws li chloromethane yog loj. Carbon muaj electronegativity ntawm 2.5. Vim tias cov tshuaj chlorine yog electronegative ntau dua li cov pa roj carbon, chlorine rub cov electrons los ze zog rau nws tus kheej.

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 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
