Yog tias koj saib ntawm Lewis qauv rau CHF 3 nws tsis tshwm symmetrical molecule . A polar molecule tshwm sim los ntawm qhov sib npaug / unsymmetrical sib koom ntawm valence electrons. Hauv CHF 3 kev sib koom tsis sib npaug thiab muaj net dipole . Yog li ntawd, CHF 3 - yog a polar molecule.

Ib yam li ib tug yuav nug, yog chf3 polar lossis tsis polar?

Vim li no, qhov no molecule yog tsis yog - polar . Hauv CHF3, txawm li cas los xij, hydrogen tsis muaj 3 lwm cov huab cua nyob ib puag ncig nws zoo li fluorine ua. Qhov no txhais tau hais tias sab ntawm lub molecule yog tag nrho zoo dua li lwm qhov ntawm lub molecule, uas yog ntom nrog fluorine atoms unbonded electrons.

hom ntawv cog lus twg yog chf3? ntxiv; lub C-H daim ntawv cog lus hauv CHF 3 yog tsis muaj polar daim ntawv cog lus.

Kuj nug, yog ch3f ib tug polar lossis nonpolar molecule?

CH3F yog a polar molecule , txawm tias tetrahedral geometry feem ntau ua rau tsis muaj polar molecules.

Koj tuaj yeem txiav txim siab li cas yog tias lub molecule 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 daim ntawv cog lus yog ntau dua 0.4, peb xav txog cov nyiaj polar . Yog qhov sib txawv ntawm electronegativity tsawg dua 0.4, daim ntawv cog lus yog qhov tseem ceeb tsis muaj polar .) Yog tsis muaj polar bonds, cov molecule yog tsis muaj polar.
