Tib lub zog txaus nyiam ntawm cov ua hexane thiab dej cov molecules yog London rog. Yog li, ob peb ua hexane molecules yuav nkag mus rau hauv txheej dej , tab sis muaj zog txaus nyiam rog ntawm cov dej molecules khaws feem ntau ntawm cov ua hexane molecules tawm. Dej thiab hexane yog tsis txawj tag . Lawv tsis yaj hauv ib leeg.
Hauv qhov no, puas yog hexane thiab dej miscible?
Tsis muaj dab tsi txog lub dej thiab ua hexane molecules attracts ib leeg. Yog li ntawd ua hexane yog tsis soluble hauv dej.
Ib tus kuj tseem yuav nug tau, ua li cas thaum hexane sib xyaw nrog dej? Yog peb ntxiv ua hexane rau dej , cov ua hexane yuav ntab rau saum lub dej nrog tsis pom meej sib tov . Thaum a ua hexane molecule txav mus rau hauv lub dej , London rog ntawm ua hexane molecules thiab hydrogen bonds ntawm dej molecules tawg.
Hais txog qhov no, vim li cas hexane tsis yaj hauv dej?
Yog li tsis yog ua hexane los yog iodine dissolves nyob rau hauv dej . Polar thiab ionic solutes ua tsis yaj nyob rau hauv cov kuab tshuaj uas tsis yog-polar vim hais tias lawv muaj ib tug muaj zog attraction rau ib leeg tshaj li rau non-polar solvent molecules. Ua kua ua hexane cov lwg me me tau tuav ua ke los ntawm London cov tub rog tawg.
Cov kuab tshuaj twg yog hexane lossis dej?
Teb thiab Piav Qhia: Dej yuav yaj Cu (NO3) 2 C u (N O 3) 2. Hexane yuav yaj CS2 C S 2 thiab CH3 (CH2) 16CH2OH C H 3 (C H 2) 16 C H 2 O H.
