Piv txwv li, dej molecules yog tuav ua ke los ntawm hydrogen bonds ntawm lub hydrogen atom ntawm ib molecule thiab oxygen atom ntawm lwm tus (daim duab: hydrogen daim ntawv cog lus). Hydrogen Cov ntawv cog lus yog lub zog muaj zog intermolecular thiab muaj zog dua li lwm cov dipole-dipole rog.

Ib yam li ntawd, koj tuaj yeem nug, hom kev sib cog lus dab tsi ntawm cov dej molecules?

Hydrogen daim ntawv cog lus yog daim ntawv cog lus nruab nrab hydrogen nyob rau hauv ib tug polar molecule thiab qhov tsis zoo them kawg ntawm lwm tus polar molecule . Hydrogen daim ntawv cog lus tso ob molecules los txuas ua ke ib ntus. Cov dej molecules yog tsim los ntawm ob lub hydrogen atoms thiab ib tug oxygen atom, tuav ua ke los ntawm polar covalent daim ntawv cog lus.

Ib tug kuj yuav nug, yog vim li cas lub zog intermolecular muaj nyob nruab nrab ntawm cov dej molecules? Dej muaj polar O-H bonds. Qhov tsis zoo O atoms nyiam qhov zoo H atoms nyob ze molecules , ua rau lub zog txawv txav ntawm cov dipole-dipole zog hu ua hydrogen bond. Cov hydrogen bonds yog lub zog tshaj zog , tab sis lwm hom intermolecular kev nyiam yog tseem muaj.

Kuj paub, dab tsi yog ib qho kev sib txuas lus sib txuas hauv dej?

Hydrogen Bonds Lub zog tshaj intermolecular zog in dej yog ib tug tshwj xeeb dipole daim ntawv cog lus hu ua hydrogen daim ntawv cog lus . Hauv dej , ib lub molecule tuaj yeem tsim txog li plaub hydrogen daim ntawv cog lus , nrog ib tug molecule rau txhua hydrogen atom thiab nrog ob hydrogen atoms ntawm qhov tsis zoo oxygen sab.

Dab tsi ntawm daim ntawv cog lus yog dej?

Dej yog ib tug polar molecule A dej molecule yog tsim thaum ob atoms ntawm hydrogen daim ntawv cog lus covalently nrog ib tug atom ntawm oxygen. Hauv covalent daim ntawv cog lus electrons sib koom ntawm atoms. Hauv dej kev sib koom tsis sib npaug. Cov pa oxygen atom nyiam cov electrons ntau dua li cov hydrogen.
