Polarity tshwm sim los ntawm kev sib faib tsis sib npaug ntawm valence electrons. Hauv CH 4 kev sib koom yog sib npaug. Yog li ntawd CH 4 yog ib tug nonpolar molecule. Thaum tej zaum yuav muaj qhov sib txawv hauv electronegativity ntawm Carbon thiab Hydrogen bonds, tsis muaj net (tag nrho) polarity.

Hauv qhov no, qhov polarity ntawm ch4 yog dab tsi?

Methane (CH4) tsis yog polar hydrocarbon compound tsim tawm ntawm ib qho carbon atom thiab 4 hydrogen atoms. Methane tsis yog polar Raws li qhov sib txawv hauv electronegativities ntawm carbon thiab hydrogen tsis zoo txaus los tsim cov tshuaj polarized.

Qhov thib ob, yog vim li cas methane ch4 yog nonpolar compound? Cov molecule methane muaj plaub Carbon-Hydrogen tib covalent bonds. Covalent bonds hu ua tsis muaj polar covalent bonds vim. Qhov tshwm sim ntawm qhov sib npaug sib npaug ntawm electrons yog tias tsis muaj kev sib cais (dipole lub sijhawm).

Qhov thib ob, yog ch4 polar lossis nonpolar molecule?

Tsis muaj . Nws yog tsis polar . Txij li tag nrho cov Hydrogen atoms sib npaug sib npaug ntawm Carbon atom, txawm tias C-H daim ntawv cog lus polar , tag nrho cov ncej tshem tawm ib leeg tawm, yog li qhov tshwm sim yog tias Methane ( CH 4 ) yog tsis yog - polar thiab insoluble hauv dej.

Puas yog HCL polar lossis nonpolar?

HCL yog a polar molecule li chlorine muaj ntau dua electronegativity tshaj hydrogen. Yog li, nws nyiam cov khoom siv hluav taws xob kom siv sij hawm ntau thaum nws kawg, muab nws tus nqi tsis zoo thiab hydrogen rau qhov zoo. Koj puas paub tias Br2 yog li cas polar los yog nonpolar ?
