Dej molecules Hauv paus, H2O molecules , uas muaj khoov duab. Yog li, tag nrho cov electron ceev ntawm ob lub hydrogen atoms tau txais kev nyiam ntawm oxygen atom. Yog li qhov polarity tsim nyob rau hauv txhua O-H daim ntawv cog lus yog li ntawd, dej molecules yog polar nyob rau hauv qhov thiab ua nyiam "me ntsis hlau nplaum ".

Tib neeg kuj nug, yog polar molecules magnetic?

Hauv qhov tsis muaj Sib nqus teb, polar molecules yog positioned random. Yog li, lawv cov nqi tsis zoo thiab qhov zoo tsis tuaj yeem txuas rau ib leeg, txawm tias kev sib tsoo ntawm cov molecules tshwm sim.

Tom qab, lo lus nug yog, hom molecules polar lossis nonpolar dissolves hauv dej? Vim cov dej molecules yog polar, lawv cuam tshuam nrog cov sodium thiab chloride ions . Feem ntau, polar solvents dissolve polar solutes, thiab nonpolar solvents dissolve nonpolar solutes. Lub tswv yim no feem ntau hais tias "Zoo li dissolves nyiam."

Kuj Paub, vim li cas cov polar molecules ua zoo li cov hlau nplaum tsis muaj zog?

Nws ua ib me ntsis nyiam a hlau nplaum nrog ob tug ncej. ncej av! Polar molecules (xws li raws li dej) ua tau sib nyiam vim lawv ib nrab (+) thiab (-) tsub. Hydrogen bonds tsis muaj zog tshaj covalent lossis ionic bonds.

Dab tsi ua rau lub molecule ua polar?

Hauv chemistry, polarity yog kev sib cais ntawm cov nqi hluav taws xob ua rau a molecule los yog nws cov pab pawg tshuaj muaj ib lub sij hawm hluav taws xob dipole, nrog rau qhov tsis zoo them kawg thiab qhov zoo them kawg. Polar molecules yuav tsum muaj polar bonds vim qhov sib txawv hauv electronegativity ntawm cov atoms sib txuas.
