Molecular Geometry

A B
Dab tsi yog qhov zoo o2 ? kab tawm
Dab tsi yog qhov puab ntawm PH3? trigonal pyramidal
Dab tsi yog qhov puab ntawm HClO? khoov
Dab tsi yog qhov puab ntawm N2? kab tawm

Yog li ntawd, lub cev molecular ntawm oxygen yog dab tsi?

Siv cov ntaub ntawv no thiab Table 3.1 peb pom tias cov molecular zoo yog tetrahedral. Central atom yog oxygen (koj tuaj yeem pom qhov no los ntawm kev kos duab molecules Lewis daim duab). Muaj ob lub tshuab hluav taws xob nyob ib puag ncig oxygen thiab ob leeg ib leeg. Cov molecule muaj cov qauv dav dav (ext{AX}_{2} ext{E}_{2}).

Ib sab saum toj, vim li cas o2 trigonal planar? O atom yog sp2 hybridized thiab nws cov qauv yog trigonal txoj kev . Yog li, ib qho O atom muaj ib daim ntawv cog lus (doube daim ntawv cog lus) thiab ob lub lonepairs. Txij li thaum peb xav txog cov duab peb tsis suav nrog cov khub ib leeg, tsuas yog ib qho kev sib cog lus ua rau nws cov duab linear. Tab sis nws tus qauv los yog geometry yog trigonal txoj kev.

Ib yam li ntawd, tib neeg nug, yog o2 linear lossis khoov?

Cov oxygen muaj 6 valence electrons thiab yog li xav tau 2 ntau electrons los ntawm 2 hydrogen atoms kom tiav nws octet. Lub molecule yog ob sab thiab khoov as opposed to beryllium hydride case uas yog a kab tawm los yog txoj kab ncaj nraim molecular geometry vim nws tsis muaj ib leeg electron khub.

Lub kaum sab xis ntawm o2 yog dab tsi?

Lub trioxygen molecule O3 muaj ib tug ib leeg thiab ua ib tug khoov duab nrog daim ntawv cog lus cov ces kaum ntawm 118 degrees. Ntawm qhov tod tes, O2 muaj ob leeg ib khub thiab ib tug linear duab.
