(1), (3) H2O thiab NH3 yog cov molecules uas muaj polar covalent bonds , tab sis lawv cov khoom siv hluav taws xob tsis sib xws. (4) H2 yog ib tug nonpolar molecule uas muaj ib tug symmetrical tis ntawm electrons, tab sis cov nyiaj ntawm cov hydrogen atoms yog nonpolar covalent.

Yog li ntawd, tus qauv twg uas sawv cev rau cov tsis muaj polar molecules?

A) H2O B) Cov qauv twg sawv cev rau qhov tsis muaj polar molecule uas muaj polar covalent bonds ?

Tsis tas li ntawd, cov molecules twg yog nonpolar vim tias txhua daim ntawv cog lus tsis yog polar? Thiab cov molecules uas yog nonpolar vim hais tias tag nrho cov bonds yog nonpolar Hydrogen (H2), Chlorine (Cl2), Nitrogen (N2), thiab Oxygen (O2) tag nrho cov no tsis muaj polar vim lawv yog tib hom ntsiab thiab lawv ob leeg muaj tib tus lej ntawm electronegativity.

Tsis tas li ntawd, yuav ua li cas lub molecule yuav nonpolar yog hais tias nws muaj polar bonds?

A molecule tau muaj polar bonds thiab tseem yuav tsis muaj polar . Yog tus polar bonds yog sib npaug (los yog symmetrically) faib, cov daim ntawv cog lus dipoles tshem tawm thiab tsis tsim ib qho molecular dipole.

Qhov twg molecule yog nonpolar?

Nonpolar Molecule Piv Txwv Piv txwv ntawm homonuclear nonpolar molecules yog oxygen (O2nitrogen (N2), thiab ozone (O3). Lwm cov nonpolar molecules muaj xws li carbon dioxide ( CO2 ) thiab cov organic molecules methane ( CH4 ), toluene, thiab roj av. Cov pa roj carbon ntau yog cov tsis muaj polar. Ib qho tshwj xeeb tshwj xeeb yog carbon monoxide, CO.
