Tawm = tsuas yog kab ntawm atoms nrog lub kaum sab xis 180 °. Nco ntsoov tias nws yog 2 lossis 3 atoms tag nrho. Khoov = Tawm tab sis khoov vim tus Lone Pairs uas nws muaj, tus ntau Lone Pairs tus ntau dua qhov khoov thiab tus me me tus degree.

Nyob rau hauv no hais txog, koj yuav ua li cas paub yog hais tias ib tug Lewis qauv yog khoov los yog linear?

Yog Tag nrho cov electrons khub yog ua raws li kev sib txuas ntawm electrons, tawm hauv tsis muaj ib khub ntawm lub hauv paus atom, ces cov molecule yuav kab tawm (eg; CO2). Yog , txawm li cas los xij, muaj ib lossis ob leeg ib leeg ntawm lub hauv paus atom, ces cov molecule yuav khoov (eg; SO2, H2O).

Tsis tas li ntawd, yog CCl4 khoov lossis linear? Raws li tus qauv Lewis, CCl4 yog tetrahedral molecule. Lub electronegativity rau C yog 2.5 thiab Cl yog 3.0, uas ua rau lub polar covalent daim ntawv cog lus. Qhov tseeb, txij li thaum lub molecule yog symmetrical, tag nrho cov dipole lub sij hawm yuav tshem tawm ib leeg tawm. CCl4 yog ib qho piv txwv ntawm ib tug nonpolar molecule.

Hauv qhov no, 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.

Puas yog SCl2 khoov lossis linear?

SCl2 yog Sulfur Dichloride. Nws muaj ib tug Sulfur thiab ob chlorine molecules. Lub npe geometry yog khoov (tetrahedral). Rau nws yog tias nws yuav tsum muaj 2 tus lej ntawm kev sib txuas lus thiab 2 ib leeg ntawm electrons.
