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.
