Tag nrho dipole ntawm ib lub molecule kuj nyob ntawm qhov geometry. Lub geometry ntawm BCl3 yog cov qauv nrog lub kaum sab xis ntawm 120 degree. Qhov tshwm sim ntawm dipole ntawm ob daim ntawv cog lus B-Cl tshem tawm qhov thib peb, ua rau net zero dipole.
Dab tsi ua rau lub sijhawm xoom dipole?
Ib qho piv txwv zoo ntawm ib qho tsis muaj polar molecule uas muaj polar bonds yog carbon dioxide (Daim duab 3a). … Txawm li cas los xij, txij li cov molecule yog linear, ob daim ntawv cog lus dipoles tshem tawm ib leeg tawm (piv txwv li vector ntxiv ntawm dipoles sib npaug zero) thiab tag nrho cov molecule muaj xoom dipole lub sij hawm (μ=0).
Puas BCl3 puas muaj lub sijhawm dipole?
BCl3, piv txwv li, tsis muaj lub sijhawm dipole , hos NH3 ua. Qhov no qhia tias hauv BCl3 cov chlorines nyob ib ncig ntawm boron yog nyob rau hauv ib qho kev npaj trigonal, thaum cov hydrogens nyob ib ncig ntawm nitrogen nyob rau hauv NH3 yuav muaj tsawg symmetrical. kev npaj (piv txwv li, trigonal pyramidal, T-shaped).
Dab tsi yog lub sijhawm dipole hauv BCl3?
Nyob rau hauv BCl3, lub hauv paus B atom undergoes sp2 hybridization uas ua rau lub dav hlau daim duab peb sab geometry. Cov molecule muaj symmetry thiab tus kheej daim ntawv cog lus dipoles thim ib leeg. Li no, cov molecule muaj zero dipole moment.
Puas BCl3 puas muaj dipole dipole rog?
BCl3 yog ib qho tsis muaj polar molecule; nws lub zog intermolecular zog yog London rog; nws muaj qhov tsawg tshaj plaws melting point. PCl3 yog ib tug polar molecule thiab nws muaj zog intermolecular rog yog dipole-dipole kev sib cuam tshuam.
