1 Teb. Tiag tiag, dej muaj tag nrho peb hom intermolecular rog , nrog lub zog tshaj yog hydrogen bonding. Txhua yam muaj London dispersion zog qhov tsis muaj zog kev sib tham yog ib ntus dipoles uas tsim los ntawm kev hloov ntawm electrons hauv ib molecule.

Yog li ntawd, hom dab tsi ntawm cov rog intermolecular muaj rau h2o?

Ernest Z. Dej muaj hydrogen bonds, dipole-induced dipole zog , thiab London dispersion zog.

Nyob rau hauv kev txiav txim ntawm kev txo lub zog, cov hom ntawm intermolecular bonds nyob rau hauv covalent tshuaj yog:

  • Hydrogen bonds.
  • Dipole-dipole attractions.
  • Dipole-induced dipole attractions.
  • London dispersion rog.

Tom qab ntawd, lo lus nug yog, hom kev sib cuam tshuam ntawm cov rog muaj nyob ntawm ch3oh thiab h2o? CH 3 OH , los yog methanol, qhia London dispersion zog thiab hydrogen bonding. London dispersion zog yog cov tsis muaj zog tshaj ntawm cov intermolecular rog.

Kuj nug, lub neej yuav zoo li cas yog tias cov dej molecules tsis tuav los ntawm hydrogen bonds?

Piv txwv li mus rau boiling kub. Qhov no ntxiv zog tuav lub dej molecules ua ke txhais tau tias dej nyob twj ywm kua ntawm chav tsev kub whereas lwm yam zoo sib xws molecules uas tsis form hydrogen bonds yog gaseous. Qhov no yog vim li cas lub neej nyob ntiaj teb no dej raws li es hais, hydrogen sulfide raws.

Dab tsi ntawm cov rog intermolecular muaj nyob hauv txhua lub molecule?

Intermolecular rog ua haujlwm ntawm cov molecules. Nyob rau hauv sib piv, intramolecular rog ua nyob rau hauv molecules. Intermolecular rog tsis muaj zog dua li cov rog intramolecular. Piv txwv ntawm cov rog intermolecular muaj xws li cov London dispersion kev sib cuam tshuam ntawm dipole-dipole, ion -dipole kev sib cuam tshuam, thiab van der Waals rog.
