Cov PH3 daim ntawv cog lus kaum Nws yuav yog li ntawm 90 degrees txij li nws muaj trigonal pyramidal molecular geometry (nws yuav tsis muaj tseeb vim tias tus khub ib leeg yuav thawb).

Tsis tas li ntawd, lub kaum sab xis zoo tshaj plaws hauv ph3 yog dab tsi?

Hauv ammonia sp3 hybridization tshwm sim. Yog li nws kev sib raug zoo yuav tsum yog 109 ° 28 '. Tab sis vim muaj ib leeg khub nws yog me ntsis tsawg. Yog li nws tau xav tias qhov PH 3 tseem yuav kwv yees li qub. Tab sis, nws tau pom nyob ib ncig ntawm 90 °.

Tom qab, lo lus nug yog, dab tsi yog qhov zoo ntawm ph3? Yog li cas PH 3 , ans yog sp3 nrog ib leeg khub soit yog pyramidal zoo li tus..

Kuj nug, dab tsi yog lub kaum sab xis ntawm phosphine?

Qauv ntawm Phosphine Cov daim ntawv cog lus H-P-H = 93°. Ntawm qhov tod tes, ammonia muaj pyramidal geometry nrog a daim ntawv cog lus ua 107.80. Yog li, peb pom tias ob qho tshuaj no muaj kev sib piv daim ntawv cog lus . Phosphorus yog tsawg dua electronegative dua nitrogen.

Vim li cas daim ntawv cog lus lub kaum sab xis ntawm pf3 ntau dua ph3?

Thaum lub daim ntawv cog lus ntawm PH 3 tsis muaj tseeb tshaj uas ntawm PF3 . Ob leeg PH 3 thiab PF3 arepyramidal nyob rau hauv cov duab. Cov daim ntawv cog lus yog ntau dua nyob rau hauv PF?3 duetolone khub- daim ntawv cog lus khub repulsion. Raws li flourine yog me me thiab ntau electronegative tshaj hydrogen, ua daim ntawv cog lus khub ntawm electrons mus rau F.
