Benzophenone , uas yog loj tsis muaj polar , tab sis muaj a polar carbonyl pawg, tau pom los ntawm bepartially soluble hauv methyl cawv thiab hexane tab sis insoluble hauv dej. Malonic acid, ib polar molecule uas tseem muaj peev xwm toionize, tau pom tias yog soluble hauv dej thiab methyl cawv butinsoluble hauv hexane.

Ib yam li ntawd, tib neeg nug, yog benzophenone polar lossis tsis polar?

Benzophenone yog insoluble nyob rau hauv dej vim wateris a polar molecule. Zoo li yaj nyiam, thiab txij li thaum benzophenone yog tsis muaj polar , qhov tshwm sim yog insoluble. Nws muaj tsis muaj polar ua haujlwm pab pawg kom nws me ntsis polar , nws yog kiag li tsis muaj polar . Hexane kuj yog tsis muaj polar , yog li biphenyl tuaj yeem yaj.

Puas yog acetone polar lossis nonpolar? Dej yog a polar molecule, thaum carbontetrachloride yog a tsis muaj polar molecule. Yog tias peb siv lub tswvyim 'likedissolves', ces acetone yog ob leeg polar thiab tsis muaj polar . Qhov no dual tus cwj pwm ntawm acetone yog vim nws lub peev xwm los ua hydrogen bonds nrog dej thiab muaj ob pawg methyl.

Cov lus nug tseem yog, puas yog biphenyl lossis benzophenone ntau dua polar?

Methanol yog nruab nrab polar , cia ob qho tib si nonpolar molecules yuav yaj raws li nws tsis dhau polar ornonpolar. Txawm li cas los xij, biphenyl yog tsawg polar tshaj benzophenone . Vim tias methyl cawv yog me ntsis polar , cov ntau polar benzophenone yog ntau soluble nyob rau hauv methylalcohol dua biphenyl.

Puas yog methanol polar lossis nonpolar?

Methanol yog a polar molecule: Saib daim duab ntawm sab laug. Cov cawv (-OH) pawg tswj hwm lub molecule ua nws twv yuav raug hu polar . Lub peev xwm theelectrostatic qhia meej meej tias cov pa oxygen yog qhov tsis zoo thaum cov pa roj carbon thiab hydrogens yog ib feem zoo.
