Kev piav qhia: Trans Benzil yog Tsis Polar vim tias lub sijhawm dipole tshem tawm vim tias ob pawg tib yam yog nyob sab nraud ntawm C--------C daim ntawv cog lus. Cis Benzil yog polar vim tias lub sijhawm dipole tsis thim qhov no vim tias tib pab pawg nyob rau tib sab ntawm C------C daim ntawv cog lus li no muaj net dipolemoment.
Kuj nug, vim li cas ethyl acetate polar?
Polar molecule muaj bonddipoles, uas tsis tso tseg ib leeg. Yog li ntawd, CH3COOCH2CH3 muaj ob polar bonds (CO thiab CO) uas lawv cov bonddipoles tsis thim ib leeg. Vim li no, ethyl acetate hmoov yog a polar compound.
Ib sab saum toj, puas Benzil yaj hauv ethanol? Benzil dissolves nyob rau hauv ethanol tab sis ua tsis yog yaj hauv dej, thaum tooj liab acetate yaj hauv ob qho tib si.
Kuj Paub, puas yog acetone yog polar molecule?
Dej yog a polar molecule , thaum carbontetrachloride yog nonpolar molecule . Yog tias peb siv lub tswvyim 'likedissolves', ces acetone yog ob leeg polar thiab nonpolar. Qhov no dual tus cwj pwm ntawm acetone yog vim nws muaj peev xwm ua hydrogen bonds nrog dej thiab muaj ob pawg methyl.
Puas yog Benzil polar lossis tsis polar?
Txij li thaum benzil ua yog tsawg polar tshaj benzoin ua , a polar Cov kuab tshuaj yog siv los ua hnyav rau therecrystallization. Benzil yog tsawg soluble nyob rau hauv txias 95% ethanol tshaj benzoin ua ua rau cov benzil ua toprecipitate ua ntej. Ice-txias 95% ethanol yog siv los yaug cov crystals.

Polar molecules puas tiv thaiv cov tsis muaj polar molecules?
Polar molecules (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
Puas yog SeO3 polar lossis nonpolar?
SeO3 thiab SeO2 ob qho tib si muaj polar bonds tab sis tsuas yog SeO2 muaj lub sijhawm dipole. Peb daim ntawv cog lus dipoles los ntawm peb lub ncov qaumteb qabteb Se-O daim ntawv cog lus hauv SeO3 yuav tag nrho tshem tawm thaum summed ua ke. Li no, SeO3 yog nonpolar vim tag nrho cov molecule tsis muaj lub sij hawm tshwm sim dipole
Puas yog ib qho tsis muaj polar molecule puas muaj hydrogen bonding?
Yog hais tias lub molecule tsis yog polar, ces tsis muaj kev sib cuam tshuam dipole-dipole los yog hydrogen bonding tuaj yeem tshwm sim thiab tsuas yog ua tau intermolecular quab yuam yog lub zog van der Waals tsis muaj zog
Puas yog acetonitrile polar lossis tsis polar?
Acetonitrile muaj 5.8 polarity index.Hydrocarbons tsis-polar yog li lawv yog cov kuab tshuaj tsuas yog rau lwm yam tshuaj tsis-polar. Tsis zoo li hydrocarbons, Ethyl Cawv muaj ob pawg polar thiab non-polarchemical ntawm cov molecule
Puas yog acetone yog polar aprotic hnyav?
Txawm li cas los xij, acetone tseem suav tias yog cov kuab tshuaj polaraprotic, txawm tias qhov tseeb tias nws yog acidic, thiab tsis muaj acidic tsawg dua li cawv. Tom qab ntawd dua, acetone (thiab lwm yam carbonyl uas muaj cov kuab tshuaj) yog, qhov tseeb, cov kuab tshuaj tsis zoo thaum siv cov hauv paus muaj zog vim lawv cov acidity siab
