trigonal planar molecular geometry → trigonska planarna geometrija molekule. Trigonal planar yog ib qho qauv molecular uas tau tshwm sim thaum muaj peb daim ntawv cog lus thiab tsis muaj ib leeg nyob ib ncig ntawm lub hauv paus atom hauv cov molecule. Cov khub yog npaj raws lub hauv paus atom txoj kab nruab nrab, nrog 120 ° kaum ntawm lawv.
Cov molecules twg muaj lub hom phiaj trigonal?
Structure of boron trifluoride, piv txwv ntawm cov molecule nrog trigonal planar geometry.
Kuv yuav paub li cas yog tias kuv muaj trigonal planar?
Nyob hauv trigonal planar, muaj tsis muaj ib khub electrons nyob hauv nruab nrab atom . Tab sis nyob rau hauv trigonal pyramidal muaj ib leeg ib khub ntawm lub hauv paus atom. Lub kaum sab xis nyob rau hauv trigonal planar yog nyob ib ncig ntawm 120o, thiab hauv trigonal pyramidal, nws yog nyob ib ncig ntawm 107o.
Lub hom phiaj trigonal zoo li cas?
CEEB TOOM: Cov molecule no yog tsim los ntawm 3 qhov sib npaug sib npaug sp2 hybrid orbitals teem ntawm 120o kaum. Cov duab ntawm lub orbitals yog planar daim duab peb sab. Txij li thaum muaj ib qho atom ntawm qhov kawg ntawm txhua lub orbital, cov duab ntawm cov molecule kuj yog daim duab peb sab.
Yuav ua li cas thiaj muaj daim duab peb sab?
Yog li, $s{{p}^{2}}$hybridization muaj cov duab peb sab. Lub hauv paus atom muaj 7 valence electrons.
