Hydrogen daim ntawv cog lus yog lub npe muab rau kev sib cuam tshuam electrostatic ntawm tus nqi zoo ntawm a hydrogen atom thiab tus nqi tsis zoo ntawm cov pa oxygen atom ntawm ib tug nyob sib ze molecule. Cov covalent bond yog electrostatic kev sib cuam tshuam ntawm ob lub atoms hauv lub ib yam molecule.

Ib yam li ntawd, tej zaum koj yuav nug tias, daim ntawv cog lus hydrogen txawv li cas ntawm covalent daim ntawv cog lus?

Covalent daim ntawv cog lus yog ib qho tshuaj lom neeg daim ntawv cog lus tsim los ntawm kev sib koom ntawm electron khub. Covalent bonds muaj zog daim ntawv cog lus nrog ntau dua daim ntawv cog lus zog. Hydrogen daim ntawv cog lus yog ib tug tsis muaj zog electrostatic attraction ntawm lub hydrogen thiab electronegative atom vim lawv txawv hauv electronegativity.

Ib tug kuj yuav nug, yog hydrogen daim ntawv cog lus muaj zog dua covalent daim ntawv cog lus? Hydrogen daim ntawv cog lus yog tsim los ntawm cov tsis muaj zog electrostatic attraction rog ntawm tus ncej zoo ntawm ib tug molecule thiab tus ncej tsis zoo ntawm lwm molecule feem ntau ntawm tib yam khoom. Yog li nws yog ntau muaj zog dua covalent daim ntawv cog lus . Yog li ntawd, lub hydrogen daim ntawv cog lus yog qaug zog heev tshaj covalent bond thiab ionic daim ntawv cog lus.

Qhov thib ob, yog hydrogen yog covalent daim ntawv cog lus?

A covalent bond yog tshuaj daim ntawv cog lus uas yog los ntawm kev sib koom ntawm ib lossis ntau dua electron khub ntawm ob lub atoms. Hydrogen yog ib qho piv txwv ntawm qhov yooj yim heev covalent compound.

Puas yog hydrogen bonds covalent lossis noncovalent?

Noncovalent bonds tsis muaj zog tshaj covalent bonds tab sis lawv tseem ceeb heev rau cov txheej txheem biochemical xws li kev tsim ntawm ob lub helix. Muaj plaub feem ntau hais txog qhov tseem ceeb noncovalent daim ntawv cog lus hom. Lawv suav nrog kev sib cuam tshuam electrostatic, hydrogen bonds , van der Waals kev sib cuam tshuam, thiab kev sib cuam tshuam hydrophobic.
