London dispersion quab yuam yog lub zog intermolecular tsis muaj zog uas tshwm sim los ntawm kev txav ntawm electrons uas tsim ib ntus dipoles hauv cov molecules. Lub London dispersion quab yuam qee zaum hu ua 'Van der Waals force.
Puas yog London yuam tib yam li Van der Waals?
London Dispersion Forces
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 txawv. … London dispersion rog yog cov intermolecular rog uas tshwm sim ntawm atoms thiab nruab nrab ntawm nonpolar molecules los ntawm kev txav ntawm electrons.
Dab tsi yog lwm lub npe rau van der Waals dispersion rog?
Kev sib cuam tshuam ntawm tus kheej van-der-Waals yog qhov tsis muaj zog ntawm cov molecules uas nyob ze rau ib leeg. Lawv tseem hu ua London dispersion rogYeej, raws li ob lub atom los ze zog rau ib leeg, qhov kev nyiam no nce mus txog thaum lawv sib cais los ntawm van-der-Waals kev sib cuag.
Peb hom van der Waals yog dab tsi?
Peb hom van der Waals muaj xws li: 1) dispersion (tsis muaj zog), 2) dipole-dipole (nruab nrab), thiab 3) hydrogen (muaj zog). Ion-dipole bonds (Ionic hom rau covalent molecules) yog tsim ntawm ions thiab polar molecules.
London dispersion rog tseem hu ua dab tsi?
Lub zog London dispersion yog lub zog tsis muaj zog tshaj plaws. … Lub zog no qee zaum hu ua induced dipole-induced dipole attraction London rog yog cov rog txaus nyiam uas ua rau cov khoom tsis muaj polar condense rau cov kua thiab khov rau hauv cov khib nyiab thaum qhov kub thiab txias qis txaus.
