Cov kuab tshuaj feem ntau categorized li polar lossis nonpolar, ib qho ntawm cov kuab tshuaj tus qauv thiab nqi uas txiav txim siab hom tshuaj uas nws tuaj yeem yaj. Polar cov kuab tshuaj muaj qhov "zoo" thiab "tsis zoo" nqi ntawm ntau qhov chaw hauv lawv cov qauv thiab yuav yaj lwm cov tshuaj polar.
Puas yog cov kuab tshuaj ntau tshaj polar?
Feem ntau, qhov dielectric qhov tas li ntawm cov kuab tshuaj muab ib qho kev ntsuas ntxhib ntawm cov kuab tshuaj polarity. Lub zog polarity ntawm dejyog qhia los ntawm nws qhov siab dielectric tas li ntawm 88 (ntawm 0 ° C). Cov kuab tshuaj nrog lub dielectric tas li ntawm tsawg dua 15 feem ntau suav tias yog nonpolar.
Dab tsi ua rau qhov hnyav polar?
Polar cov kuab tshuaj muaj lub sijhawm loj dipole (aka "cov nqi ib nrab"); lawv muaj cov ntawv cog lus ntawm atoms nrog cov electronegativities sib txawv, xws li oxygen thiab hydrogenCov kuab tshuaj tsis muaj polar muaj cov ntawv cog lus ntawm cov atoms nrog cov electronegativities zoo sib xws, xws li carbon thiab hydrogen (xav tias hydrocarbons, xws li roj av).
Puas yog polar molecules solvents?
A polar molecule nrog ib nrab-zoo thiab tsis zoo nqi, nws npau yaj ions thiab polar molecules. Cov dej yog li ntawd hu ua cov kuab tshuaj: ib yam khoom muaj peev xwm ntawm dissolving lwm polar molecules thiab ionic compounds.
Dab tsi yog qhov txawv ntawm qhov tsis muaj polar thiab polar solvents?
Qhov sib txawv tseem ceeb ntawm polar thiab nonpolar cov kuab tshuaj yog qhov polar solvents dissolve polar compounds, whereas nonpolar solvents dissolve nonpolar compounds. Yog li, nws ua rau ib nrab nqi zoo thiab ib nrab nqi tsis zoo hauv tib qho chaw. …

Puas yog kas fes yog kuab los yog kuab tshuaj?
Thaum koj brew kas fes, koj tab tom tsim kev daws teeb meem. Cov me me ntawm cov hauv paus kas fes, los yog cov kuab tshuaj, yog dissolved hauv dej, cov kuab tshuaj . Puas yog khob kas fes yog kuab los yog kuab tshuaj? Cov qab zib uas koj ntxiv rau hauv khob kas fes yog lub npe hu ua tus soluteThaum cov kua dej no ntxiv rau cov kua, uas yog hu ua cov kuab tshuaj, cov txheej txheem dissolving pib.
Koj puas ntxiv cov kuab tshuaj rau cov kuab tshuaj?
Mov kom huv si kom yaj lub solute Thaum cov kuab tau yaj lawm, ntxiv cov kuab tshuaj uas tseem tshuav los ua cov tshuaj uas xav tau ntim thiab sib tov kom huv si. Piv txwv li, ua 0.5 Litres ntawm 0.5 molar NaCl: … Ua ib qho kev daws teeb meem ntawm ib qho concentration ntawm cov tshuaj hauv Tshuag yog hu ua dilution .
Puas yog hexylene glycol polar lossis nonpolar?
Cov ntaub ntawv ntawm nplooj ntawv no: Ib txwm alkane RI, tsis-polar kab, kev cai ntsuas kub. References . Puas yog hexylene glycol dej soluble? Hexylene Glycol lossis HG yog cov kuab tshuaj oxygenated tau los ntawm acetone uas muaj ob txoj haujlwm cawv.
Puas yog borane polar lossis nonpolar?
BH3 (Borane) yog a nonpolar khoom vim yog symmetrical trigonal planar geometry. Lub electronegativity ntawm Boron (2.04) thiab Hydrogen (2.20) atoms yog ze li qhov qub vim tias B-H daim ntawv cog lus yuav luag tsis muaj polar . Puas yog CHF3 polar lossis nonpolar?
Puas yog fluoranthene polar lossis nonpolar?
Fluoranthene yog polycyclic aromatic hydrocarbon (PAH). Cov molecule tuaj yeem pom raws li kev sib xyaw ntawm naphthalene thiab benzene chav tsev txuas nrog tsib lub nplhaib. Txawm hais tias cov qauv feem ntau daj ntseg daj, cov khoom sib xyaw tsis muaj xim.
