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.
