Dipole-dipole kev sib cuam tshuam yog ib hom kev sib cuam tshuam-kev nyiam ntawm ob lub molecules… Ib qho hluav taws xob monopole yog ib qho nqi, thaum lub dipole yog ob qho tib si sib txawv nyob ze rau txhua qhov lwm yam. Cov molecules uas muaj dipoles hu ua polar molecules thiab muaj ntau heev nyob rau hauv xwm.
Dab tsi yog 5 hom kev sib cuam tshuam ntawm lub zog?
Muaj tsib hom kev sib cuam tshuam: ion-dipole rog, ion-induced-dipole rog, dipole-dipole rog, dipole-induced dipole rog thiab induced dipole rog.
3 lub zog sib cuam tshuam yog dab tsi?
Muaj peb hom kev sib cuam tshuam: London dispersion rog (LDF), kev sib cuam tshuam dipole- dipole, thiab hydrogen bonding. Molecules tuaj yeem muaj kev sib xyaw ntawm peb hom kev sib cuam tshuam, tab sis txhua yam khoom tsawg kawg muaj LDF.
Qhov twg tsis yog lub zog cuam tshuam?
Technically hais, ionic bonds tsis yog cov rog sib txuas vim tsis muaj covalent bonds. Raws li lub zog ntawm daim ntawv cog lus / quab yuam nce, yog li ua melting thiab boiling point.
Qhov twg yog lub zog muaj zog tshaj plaws?
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 lub hydrogen nyob ze ze (kho rau) lub ntsiab lus electronegative heev (xws li oxygen, nitrogen, lossis fluorine).
