Qhov twg d orbitals yog koom sp3d2 ua 2sp3 hybridization raws? Teb: sp3 d 2 los yog d 2sp3 yog hybridization rau theoctahedral geometry. Nyob rau hauv octahedron, cov ntawv cog lus tau tsim parallelto rau x, y, thiab z-axes, yog li dx2-dy2 anddz ua2 yuav siv tau los ua hybrid orbitals.

Tsis tas li ntawd, qhov twg d orbital koom nrog sp3d hybridization thiab vim li cas?

ua dsp2 hybridization favors ib daim duab geometryin uas plaub hybridized orbitals pw hauv lub dav hlau equatorialxy, xws li hauv ICl4- lossis XeF4. Yog li, dx^2-dy^2 orbital siv dsp2 hybridization , nrog rau s, px thiab py orbitals los ua ib tug square planar geometry.

Ib sab saum toj no, qhov txawv ntawm sp3d2 thiab d2sp3 yog dab tsi? Hloov pauv hlau tuaj yeem pom d2sp 3 hybridization qhov twg d orbitals yog los ntawm 3d thiab s thiab p orbitals yog 4s thiab 3d. Cov kab hauv qab yog qhov no, hauv sp3d 2 hybridization tag nrho cov orbitals muaj tib lub ntsiab quantumnumber. Hauv lwm lo lus, tsis muaj sp3d 2 hybridization hauv SF6.

Xav txog qhov no, dab tsi yog sp3d2 hybridization?

sp3d2 hybridization ua muaj 1s, 3p thiab 2d orbitals, uas undergo intermixing rau daim ntawv 6 zoo tib yam sp3d 2 hybridorbitals. Cov 6 orbitals no yog coj mus rau cov ces kaum ntawm anoctahedron. Lawv inclined ntawm lub kaum sab xis ntawm 90 degrees rau ib leeg.

Dab tsi yog qhov txawv ntawm dsp3 thiab sp3d?

Hauv sp3d ua hybridization lub d orbital ntawm nth plhaub koom hauv tsim ntawm hybridorbitals, whereas nyob rau hauv dsp3 ua hybridization ntawm d-orbital ntawm (n-1)th plhaub koom nrog hauv hybridization.
