Lub zog muaj zog tshaj plaws yog hydrogen bonding, uas yog ib qho tshwj xeeb ntawm kev sib cuam tshuam ntawm dipole-dipole uas tshwm sim thaum hydrogen nyob ze (kho rau) lub ntsiab lus electronegative heev (xws li oxygen, nitrogen, lossis fluorine).
Vim li cas van der Waals quab yuam yog qhov tsis muaj zog tshaj?
Dispersion rog kuj suav hais tias yog hom van der Waals quab yuam thiab yog qhov tsis muaj zog tshaj plaws ntawm txhua lub zog sib xyaw. Lawv feem ntau hu ua London rog tom qab Fritz London (1900-1954), uas thawj zaug tshaj tawm lawv lub neej nyob rau xyoo 1930.
Lub ntsiab lus twg muaj lub zog van der Waals?
Lub cev lub cev ntawm chav ntsuas kub Lub zog tawg yog qhov muaj zog tshaj plaws rau
iodine molecules vim tias lawv muaj cov hluav taws xob ntau tshaj plaws. Lub zog muaj zog ua rau cov ntsiab lus melting thiab boiling uas yog qhov siab tshaj plaws ntawm pawg halogen.
Yuav ua li cas 3 hom van der Waals thiab rank lawv ntawm zog tshaj mus rau qaug zog?
Covalent compounds nthuav tawm van der Waals intermolecular rog uas tsim cov ntawv cog lus ntawm ntau lub zog nrog rau lwm cov khoom sib txuas. Peb hom van der Waals muaj xws li: 1) dispersion (tsis muaj zog), 2) dipole-dipole (medium), thiab 3) hydrogen (muaj zog).
Qhov twg muaj zog dua van der Waals lossis hydrogen bonds?
Hydrogen daim ntawv cog lus tuaj yeem txhais tau tias yog lub zog txaus nyiam ua haujlwm ntawm hydrogen atom ntawm ib lub molecule nrog lub electronegative atom (F, O lossis N) ntawm lwm cov molecule. … Hydrogen bonds muaj zog dua van der Waals rog vim H-bonds raug suav tias yog ib qho kev sib cuam tshuam ntawm dipole-dipole.
