Intermolecular rog (IMF) yog cov zog uas kho kom haum xeeb kev sib cuam tshuam ntawm molecules, suav nrog zog ntawm attraction los yog repulsion uas ua ntawm molecules thiab lwm yam ntawm cov nyob sib ze hais, e.g. atoms los yog ions. Ob txheej ntawm zog yog qhov tseem ceeb ntawm zog cov teb nquag siv hauv molecular mechanics.
Ib yam li ntawd, dab tsi yog lub zog intermolecular thiab piv txwv?
Intermolecular rog ua ntawm molecules. Nyob rau hauv sib piv, intramolecular zog ua nyob rau hauv molecules. Intermolecular rog tsis muaj zog tshaj intramolecular zog . Piv txwv ntawm intermolecular rog suav nrog London dispersion zog , dipole-dipole kev sib cuam tshuam, ion-dipole kev sib cuam tshuam, thiab van der Waals zog.
Tsis tas li ntawd, dab tsi yog qhov sib txawv ntawm cov rog ua los ntawm? Intermolecular rog yog electrostatic nyob rau hauv cov xwm; uas yog, lawv tshwm sim los ntawm kev sib cuam tshuam ntawm cov tsiaj zoo thiab tsis zoo. Zoo li covalent thiab ionic Cov ntawv cog lus, kev sib cuam tshuam ntawm intermolecular yog cov txiaj ntsig ntawm ob qho tib si ntxim nyiam thiab ntxim nyiam.
Tsis tas li ntawd, dab tsi yog qhov sib txawv ntawm cov rog rog yooj yim txhais?
Cov intermolecular lub zog yog tag nrho ntawm cov zog nruab nrab ntawm ob tug nyob sib ze molecules. Hydrogen bonding yog suav tias yog ib hom kev sib cuam tshuam ntawm dipole-dipole, thiab yog li pab txhawb rau lub vas intermolecular zog. Nyob rau hauv sib piv, intramolecular quab yuam yog cov sum ntawm cov zog uas ua nyob rau hauv ib lub molecule ntawm nws cov atoms.
Dab tsi yog hom ntawm intramolecular rog?
Intramolecular bonds yog cov ntawv cog lus uas tuav cov atoms rau atoms thiab ua cov tebchaw. Muaj 3 hom intramolecular bonds: covalent, ionic, thiab metallic. Covalent Bond: ib daim ntawv cog lus uas ib khub lossis khub ntawm electrons sib koom los ntawm ob lub atom.

Dab tsi yog qhov sib txawv ntawm cov rog yuav cuam tshuam rau kev sib cuam tshuam ntawm cov dej molecules?
1 Teb. Qhov tseeb, dej muaj tag nrho peb hom kev sib xyaw ua ke, nrog qhov muaj zog tshaj plaws yog hydrogen bonding. Txhua yam muaj London dispersion yuam cov kev sib cuam tshuam tsis muaj zog yog ib ntus dipoles uas tsim los ntawm kev hloov ntawm electrons nyob rau hauv ib lub molecule
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
Lub xeev twg ntawm cov teeb meem twg muaj zog tshaj intermolecular rog ntawm attraction?
Raws li qhov kub thiab txias tseem poob qis, qhov teeb meem tsim muaj zog. Vim tias cov khoom tsis muaj zog kinetic, cov khoom tsis muaj 'lub sij hawm' txav mus los, cov khoom muaj 'lub sij hawm' kom nyiam. Yog li ntawd, cov khib nyiab muaj qhov muaj zog tshaj plaws intramolecular rog (vim lawv muaj qhov muaj zog tshaj plaws)
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
Yam dab tsi ntawm cov rog intermolecular yog active nyob rau hauv lub xeev cov kua?
Dab tsi ntawm cov rog intermolecular muaj zog hauv cov kua hauv lub xeev ntawm txhua yam hauv qab no? a) Neon (Ne) yog cov roj zoo. Cov rog uas muaj nyob hauv cov roj atoms thiab cov tsis muaj polar molecules yog hu ua dispersion rog. Yog li, nyob rau hauv cov kua neon dispersion quab yuam yog active
