Ib yam li ib tug yuav nug, puas yog toluene polar lossis tsis polar?

Toluene yog tsis muaj polar . Tsis muaj polar Cov kuab tshuaj muaj kev sib txuas ntawm cov atoms uas muaj feem cuam tshuam nrog electronegativities, xws li carbon thiab hydrogen. Polar Cov kuab tshuaj muaj cov atom nrog cov electronegativities sib txawv, xws li hydrogen thiab oxygen.

Tsis tas li ntawd, vim li cas toluene tsis yog polar? Toluene yog hydrocarbon (C7H8) thiab vim yog qhov sib txawv me me hauv electronegativties ntawm C thiab H, lawv daim ntawv cog lus suav tias yog tsis muaj polar . Ua ib qho hydrocarbon, toluene yog ib qho molecule uas tag nrho cov khi yog tsis muaj polar thiab nyob rau hauv lem ua nws ib tsis muaj polar molecule.

Hauv qhov no, puas yog toluene ntau dua polar dua dej?

Ua haujlwm rau Polar thiab Dej - Soluble Solvents. Extraction raws tu qauv rau Polar Cov kuab tshuaj.

Cov kuab tshuaj thiab Polarity.

Solvent kwv tij polarity
toluene 0.099
tshuaj benzene 0.111
ether 0.117
methyl t-butyl ether (MTBE) 0.124

Dab tsi yog polar benzene lossis toluene ntau dua?

Yog vim li cas tshuaj benzene a polar molec, nws polarity tseem loj dua toluene ? Nws yog polar vim nws muaj quadrupole lub sij hawm, thiab hais tias nws yuav ua tau electrostatic attraction nrog polar molecules xws li H2O thiab NH3, zoo li cov dej molecule cov ntaub ntawv complexes nrog lub polar molecules.
