Higher lub zog sib cuam tshuam ntawm cov kua dej, nyuaj dua rau nws kom khiav mus rau theem vapor, piv txwv li, koj xav tau ntau lub zog los hloov nws los ntawm cov kua rau hauv vapor theem, nyob rau hauv lwm yam lus, siab dua nws boiling point.
Puas intramolecular cuam tshuam qhov kub hnyiab?
Intermolecular rog (IMFs) tuaj yeem siv los kwv yees kwv yees cov ntsiab lus kub. Lub muaj zog dua IMFs, qhov qis dua qhov vapor siab ntawm cov khoom thiab qhov kub siab dua.
Pob intramolecular rog cuam tshuam qhov melting point?
Yog li, qhov melting taw tes yog nyob ntawm lub zog nws yuav siv los kov yeej cov rog ntawm cov molecules, lossis cov rog intermolecular, tuav lawv hauv cov lattice. Lub zog muaj zog ntau dua, yuav tsum muaj lub zog ntau dua, yog li qhov siab dua qhov melting point.
Puas yog kev sib koom ua ke ntawm cov tshuaj hydrogen hauv lub cev ua kom lub cev kub?
Peb paub tias qhov melting point, thiab boiling point ntawm ib tug molecule nyob ntawm qhov kev sib raug zoo ntawm ob molecules. Ntawd yog, cov ntsiab lus melting thiab cov ntsiab lus kub kub tsis hloov nrog kev tsim lossis tawg ntawm intramolecular hydrogen bonds. Yog li, tsis muaj qhov nce hauv qhov kub ntawm qhov sib xyaw
Yuav ua li cas lub zog cuam tshuam qhov kub?
Intermolecular rog yog lub zog txaus nyiam ntawm cov molecules. Lawv yog cov feem ntau lub luag hauj lwm rau cov pom boiling ntsiab lus thiab solubility zog ntawm molecules.
