(c) tseem ceeb vim lawv yog ntau heev . Polar attractions tshwm sim ntawm atoms nrog ib nrab nqi thiab tsis muaj zog tshaj covalent bonds. Txawm li cas los xij, lawv tseem ceeb heev vim tias muaj ntau ntawm lawv tshwm sim hauv cov hlwb.

Ua raws li qhov no saib, dab tsi yog qhov chaw zoo nkauj?

Polar attractions tshwm sim ntawm atoms nrog ib nrab nqi thiab tsis muaj zog tshaj covalent bonds. Lawv tuaj yeem tsim ntawm H thiab lwm cov atoms electronegative heev, xws li O, yog tias cov atoms muaj zog ib nrab nqi. Txhua cov dej molecule tau koom nrog _ lwm cov dej molecules los ntawm _ bonds.

Kuj Paub, muaj pes tsawg atoms nyob rau hauv daim duab molecule tuaj yeem tsim hydrogen bonds nrog dej molecule? Teb thiab piav qhia: A dej molecule tuaj yeem tsim plaub hydrogen bonds . Dej yog ua los ntawm ob hydrogen atoms thiab oxygen atom.

Piv txwv li, dab tsi yog qhov feem ntau polar bond?

O-H daim ntawv cog lus yog daim ntawv cog lus tshaj plaws vim tias muaj qhov sib txawv loj tshaj plaws hauv electronegativity.

Puas yog OO Bond Polar?

Qhov no C atom yog khi rau ob feem ntau electronegative atoms nyob rau hauv lub molecule (O), ob qho tib si yog rub cov electrons los ntawm C. Dr. Haxton hais tias O-O daim ntawv cog lus yog polar thiab C-C daim ntawv cog lus yog nonpolar. Thaum ob lub atoms ntawm tib yam tsim ib covalent daim ntawv cog lus , lawv faib cov electrons sib npaug vim lawv cov electronegativity yog tib yam.
