Nyob rau hauv lub trigonal bipyramidal qauv, ib leeg Pair occupies ib txoj hauj lwm equatorial es tsis yog txoj hauj lwm axial vim txoj hauj lwm equatorial muaj ob tug nyob sib ze ntawm 90^{othiab ob ntxiv ntawm 120}o ^{thaum txoj haujlwm axial muaj 3 tus neeg nyob sib ze ntawm 90}o ^{thiab ib qho ntawm 120}o ^{yog li qhov repulsion me dua nyob rau hauv rooj plaub ntawm equatorial …}

Puas muaj pes tsawg tus khub trigonal bipyramidal?

Yog hais tias muaj ob daim ntawv cog lus thiab ob leeg ib khub ntawm cov hluav taws xob cov molecular geometry yog angular lossis bent (xws li H2O). Tsib electron khub muab qhov pib taw tes uas yog tus qauv trigonal bipyramidal.

Lub molecule twg muaj qhov kev npaj trigonal bipyramidal?

Koj tuaj yeem pom cov qauv pob-thiab-loj ntawm phosphorus pentafluoride, sulfur tetrafluoride thiab chlorine trifluoride: tag nrho peb lub molecules muaj tsib khub ntawm cov hluav taws xob sab nraud nyob ib ncig ntawm lawv lub hauv paus atom, yog li. lawv txhua tus muaj trigonal bipyramidal kev npaj ntawm electron khub nyob ib ncig ntawm lub hauv paus atom.

Dab tsi yog cov duab ntawm trigonal bipyramidal?

Ib daim duab trigonal bipyramidal daim ntawv thaum lub hauv paus atom nyob ib puag ncig los ntawm tsib atoms hauv ib lub molecule. Nyob rau hauv lub geometry, peb atoms nyob rau hauv tib lub dav hlau nrog daim ntawv cog lus kaum ntawm 120 °; Lwm ob lub atom yog nyob ntawm qhov kawg ntawm lub molecule.

Puas yog ib khub axial lossis equatorial?

Thaum ib lub molecule muaj 5 electron khub, 2 ntawm uas yog ib leeg, cov leeg ib leeg nyob hauvlub equatorial txoj haujlwmyuam cov atoms sib txuas rau hauv "T-Shaped" molecular geometry. molecular geometry (MG) nrog ob qho I-I daim ntawv cog lus hauv txoj haujlwm axial.
