10. Thaum huab cua electron nyob ib ncig ntawm ib lub molecule tsis faib symmetrically, ib lub molecule yog polar. 11. Chemical bonds muaj xws li ionic bonds thiab hydrogen bonds.
Thaum huab cua hluav taws xob tsis tau muab faib ua symmetrically lub molecule raug suav tias yog polar?
Intermolecular rog tshwm sim los ntawm kev sib cuam tshuam ntawm electron ntawm cov nyob sib ze molecules. Thaum huab cua hluav taws xob tsis tau faib symmetrically, lub molecule muaj qhov polarity. Cov ntawv cog lus tshuaj muaj xws li ionic bonds, metallic bonds, thiab atomic bonds. 3.)
Cov polarity ntawm ib yam khoom cuam tshuam li cas rau lub zog ntawm kev nyiam ntawm cov molecules?
Polar molecules sib dhos kom qhov kawg ntawm ib lub molecule cuam tshuam nrog qhov tsis zoo kawg ntawm lwm cov molecule. Tsis zoo li covalent bonds ntawm atoms nyob rau hauv ib lub molecule (intramolecular bonding), dipole-dipole kev sib cuam tshuam tsim kev nyiam ntawm cov khoom ntawm cov khoom(intermolecular attractions).
Yuav ua li cas electronegativity cuam tshuam rau lub zog ntawm lub cev?
Qhov txawv ntawm electronegativity ntawm ob lub atoms hauv daim ntawv cog lus txiav txim seb hom ntawv cog lus uas tsim. … Intermolecular rog, xws li dipole-dipole rog, London dispersion rog, thiab hydrogen bonds, yog qaug zog zog uas muaj nyob nruab nrab ntawm molecules.
Dab tsi yog qhov kev sib cuam tshuam molecular uas 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 hydrogen nyob ze (kho rau) lub ntsiab lus electronegative heev (xws li oxygen, nitrogen, lossis fluorine).
