Lawv daim ntawv cog lus dipoles tsis tso tseg, yog li cov molecule yog polar . Ntawm qhov tod tes, XeF4 muaj ob leeg ib leeg ntawm Xe. Qhov no yog tus lej sib npaug, yog li koj yuav tsum kuaj xyuas qhov zoo ntawm cov molecule. Ntawm no, Xe-F daim ntawv cog lus dipoles tshem tawm ib leeg, yog li cov molecule yog tsis muaj polar.

Xav txog qhov no, yog SbF5 polar lossis nonpolar?

SbF5 tsim cov duab trigonal bipyramidal. Muaj polar daim ntawv cog lus tam sim no thiab kuv xav tias nws yog tsis polar vim nws yog molecular geometry. Txawm li cas los xij, Lub molecule nws tus kheej tsis yog symmetrical nkaus (tshwj tsis yog kuv xav txog symmetry tsis raug).

Kuj Paub, puas yog sf5 muaj lub sijhawm dipole? Txawm hais tias lub molecule zoo li CHCl 3 yog qhov zoo tshaj plaws piav raws li tetrahedral, cov atoms khi rau carbon tsis zoo ib yam. Yog li ntawd, daim ntawv cog lus dipole moments tsis tuaj yeem tso tseg ib leeg, thiab cov molecule muaj lub sijhawm dipole.

Tom qab ntawd, lo lus nug yog, koj yuav qhia li cas tias nws yog polar lossis nonpolar?

Kauj ruam 2: Txheeb xyuas txhua daim ntawv cog lus raws li ib yam polar los yog nonpolar . ( Yog Qhov sib txawv ntawm electronegativity rau cov atoms hauv ib daim ntawv cog lus yog ntau dua 0.4, peb xav txog cov nyiaj polar . Yog qhov sib txawv ntawm electronegativity yog tsawg dua 0.4, daim ntawv cog lus yog qhov tseem ceeb tsis muaj polar .) Yog tsis muaj polar bonds, lub molecule yog tsis muaj polar.

Dab tsi yog qhov molecular geometry ntawm sf5 -?

SF6 yog octahedral puab uas ua rau kev nkag siab zoo tag nrho. SF5 + npaj 5 khub ntawm electrons hauv trigonal bipyramidal qauv.
