Cov pab pawg ua haujlwm yog pawg ntawm cov atoms nrog cov qauv thiab cov haujlwm. Polar molecules Polar molecules Nyob rau hauv chemistry, polarity yog kev sib cais ntawm cov nqi hluav taws xob ua rau cov molecule lossis nws cov chemical pawgmuaj lub sijhawm hluav taws xob dipole, nrog qhov tsis zoo them kawg thiab qhov zoo kawg nkaus. Polar molecules yuav tsum muaj polar bonds vim qhov sib txawv ntawm electronegativity ntawm cov atoms sib txuas. https://en.wikipedia.org › wiki › Chemical_polarity
Tshuaj polarity - Wikipedia
(nrog +/- tsub) yog nyiam rau cov dej molecules thiab yog hydrophilic. Nonpolar molecules yog repelled los ntawm dej thiab tsis yaj hauv dej; yog hydrophobic. … Nws lub xub ntiag yuav ua kom muaj cov molecule ua dej soluble.
YPuas yog dej hydrophilic soluble?
Ib lub hydrophilic molecule los yog ib feem ntawm ib tug molecule yog ib tug uas muaj kev cuam tshuam nrog dej thiab lwm yam polar tshuaj yog ntau thermodynamically nyiam tshaj lawv cov kev cuam tshuam nrog roj los yog lwm yam hydrophobic kuab tshuaj. … Qhov no ua rau cov molecules soluble tsis yog hauv dej xwb tab sis kuj nyob rau hauv lwm cov polar solvents.
YPuas yog hydrophobic insoluble?
Lipids suav nrog ntau pawg ntawm cov tebchaw uas tsis muaj polar nyob rau hauv qhov xwm txheej. Qhov no yog vim hais tias lawv yog cov hydrocarbons uas suav nrog feem ntau nonpolar carbon-carbon lossis carbon-hydrogen bonds. Non-polar molecules yog hydrophobic ("dej ntshai"), los yog insoluble hauv dej.
Ibhydrophobic lossis hydrophilic soluble hauv dej?
Hydrophilic tshuaj yog polar nyob rau hauv xwm. 'Zoo li yaj zoo li' txoj kev xav tswj xyuas qhov tseeb tias cov tshuaj hydrophilic zoo li yooj yim yaj hauv dej lossis cov kuab tshuaj polar thaum cov tshuaj hydrophobic tsis zoo soluble hauv dej lossis polar solvents.
Koj paub li cas yog nws hydrophobic lossis hydrophilic?
lo lus no tshwm sim vim hydrophobic molecules tsis yaj hauv dej. Yog hais tias ib lub molecule muaj thaj chaw uas muaj yog ib feem zoo lossis tsis zoo, nws yog hu ua polar, lossis hydrophilic (Greek rau "kev hlub dej").
