Covalent compounds nthuav tawm van der Waals intermolecular rog uas tsim cov ntawv cog lus ntawm ntau lub zog nrog lwm cov khoom sib txuas. … Ion-dipole bonds (Ionic hom rau covalent molecules) yog tsim los ntawm ions thiab polar molecules. Cov tebchaw no feem ntau tsim cov nyiaj nruab nrab rau cov ntawv cog lus muaj zog.
Puas yog cov rog sib xyaws tsis yog covalent daim ntawv cog lus?
Intermolecular rog yog tsis-covalent kev sib cuam tshuam uas tshwm sim ntawm cov molecules sib txawv, tsis yog ntawm cov atom sib txawv ntawm tib lub molecule.
Qhov twg yog lub zog sib xyaw ua ke hauv qab no?
Plag: Ion-dipole rog yog qhov muaj zog tshaj plaws ntawm cov rog sib txawv. Hydrogen bonding yog ib lo lus tshwj xeeb rau kev sib cuam tshuam ntawm dipole-dipole ntawm hydrogen atom thiab electronegative atom (oxygen, fluorine, lossis nitrogen).
Dab tsi yog daim ntawv cog lus muaj zog tshaj plaws?
Cov nyiaj muaj zog tshaj plaws uas tsis yog-covalent yog lub npe hu ua kev sib cuam tshuam ntawm dipole-dipole ntawm ob pawg ionic ntawm qhov sib txawv nqi.
Daim ntawv cog lus intramolecular twg yog qhov muaj zog tshaj?
Feem ntau, cov rog intramolecular muaj zog dua li cov rog intermolecular. Tsis pub dhau lub zog sib xyaw ua ke,ion-dipole yogqhov muaj zog tshaj plaws, ua raws li hydrogen bonding, ces dipole-dipole, thiab tom qab ntawd London dispersion.
