Yam dab tsi ntawm cov rog intermolecular muaj zog hauv lub xeev ua kua ntawm txhua yam hauv qab no? a) Neon (Ne) yog cov roj zoo. Cov zog uas muaj nyob ntawm noble gas atoms thiab nonpolar molecules yog hu ua dispersion zog . Yog li, hauv ua kua neon dispersion lub zog muaj zog.

Ib yam li ntawd, hom dab tsi ntawm kev quab yuam intermolecular active nyob rau hauv cov kua hauv lub xeev ntawm NE?

dispersion rog

Tsis tas li ntawd, cov kua dej puas muaj lub zog sib xyaw ua ke? Cov kua dej , solids, thiab gases. Cov kua dej flow vim intermolecular rog nruab nrab ntawm cov molecules tsis muaj zog txaus kom cia cov molecules txav ib ncig ntawm ib leeg. Intermolecular rog yog cov zog nruab nrab ntawm cov molecules nyob sib ze. Nyob rau theem molecular, kua muaj qee yam khoom ntawm gases thiab qee cov khoom khib nyiab.

Nyob rau hauv no, hom dab tsi ntawm lub zog intermolecular muaj nyob rau hauv cov kua roj thiab cov khib nyiab?

Roj particles tau tawg tawm ntawm cov intermolecular rog tias tuav kua thiab khoom ua ke. Lwm lub npe rau intermolecular rog yog van der Waals zog . Lawv suav nrog London Dispersion Kev quab yuam , dipole-cov zog , thiab hydrogen bonds.

Cov kua dej twg muaj zog tshaj plaws hauv lub cev?

Dej muaj lub zog intermolecular zog (hydrogen bonds) ntawm tag nrho cov khoom siv. Glycerine thiab methylated dab kuj muaj hydrogen bonds, tab sis cov no intermolecular rog me ntsis qaug zog dua hauv dej.
