(i) Electron-deficient compounds of hydrogen: - Cov hydrides ntawm qee cov tebchaw tsis muaj hluav taws xob vim cov ntsiab lus zoo li gp 13 cov ntsiab lus tsis muaj hluav taws xob txaus. … Piv txwv ntawm cov ntsiab lus no yog C thiab Si. Lawv tsim CH4 thiab SiH4.
Vim li cas electron tsis txaus hauv SiH4?
- Yog li ntawd, nws muaj 2 electron khub tsawg tshaj li qhov xav tau ntau tshaj plaws rau kev sib txuas, uas ua rau nws tsis muaj electron.
Puas SiCl4 electron tsis txaus?
SiCl4 tsis yog electron deficient compound vim silicon muaj 8 valence electrons. Nws tsis tuaj yeem kis nws cov kev sib tw dhau 4 vim tias silicon tsis muaj d- orbitals.
Lub teb chaws twg yog electron tsis txaus?
covalent bonding
Lwm hom kev zam rau Lewis txoj hauv kev rau kev sib txuas lus yog qhov muaj nyob ntawm cov tebchaw uas muaj tsawg tsawg electrons rau Lewis qauv sau. Cov tebchaw no hu ua electron-deficient compounds. Ib qho piv txwv tseem ceeb ntawm cov khoom siv hluav taws xob tsis muaj hluav taws xob yog diborane, B 2H6…
Qhov twg hauv qab no tsis muaj hluav taws xob?
Boranes thiab carboranes raug txheeb xyuas tias yog cov khoom tsis muaj hluav taws xob hauv chemistry.
