Silane hnyav dua, yog li nws muaj cov tub rog London loj dua London rog London dispersion rog (LDF, tseem hu ua dispersion rog, London rog, instantaneous dipole-induced dipole rog, Fluctuating Induced Dipole Bonds los yog xoob li van der Waals rog.) yog hom quab yuam ua ntawm cov atoms thiab cov molecules uas ib txwm muaj hluav taws xob sib luag; uas yog, cov electrons yog … https://en.wikipedia.org › wiki › London_dispersion_force

thiab qhov kub siab dua. Nyob nruab nrab ntawm dej thiab hydrogen sulfide, ob leeg yog polar, thiab muaj dipole-dipole rog, yog li lawv muaj cov ntsiab lus kub siab dua li methane lossis silane. Tab sis dej muaj hydrogen bonds, uas yog ntxiv zog dipole-dipole rog.
Yuav ua li cas ntawm lub zog sib xyaw ua ke yog SiH4?
Tus naj npawb loj ntawm cov hluav taws xob hauv SiH4 kis thoob plaws qhov chaw loj hauv SiH4 ua rau Van der Phab ntsa dispersion rog hauv SiH4 loj dua methane. Qhov no ua rau lub zog sib xyaw ua ke hauv SiH4 loj dua CH4.
Puas SiH4 puas muaj dipole-dipole?
SiH4 tsis muaj polar nyob rau hauv cov xwm txheej vim nws cov duab sib luag muaj plaub qhov sib npaug Si-H daim ntawv cog lus tshem tawm lawv lub sijhawm dipole ua rau hauv net dipole lub sijhawm xoom.
Kuv muaj dab tsi nyob hauv SiH4?
Tshwj xeeb, zaj lus qhia piav qhia ion-dipole, dipole-dipole, thiab London (lossis dispersion) rog.
Ibmuaj hydrogen bonding hauv SiH4?
Ntawm no, Si1-H3 ntawm SiH4 ua raws li ob qho tib si ib daim ntawv cog lus hydrogen pubthiab tus pub hluav taws xob. Yog li ntawd, piv nrog cov pa hydrogen bonds, lawv tsim IHB complexes.
