Is the bond between Si and H?

I think so because the equations would have to be SiH4 and the lewis dot structure would give you a s H on each side pulling equally in each direction and I think the electrons are equally shared. What do you think?


It's just a multiple choice question asking what the bond between silicon and hydrogen would be described as. a) ionic b) dielectric (which we haven't talked about if it's even a type of bond) c) non-polar covalent d) polar covalent

    SiH4 is the silicon analogue of methane (CH4).

    There are four Si-H bonds arranged tetrahedrally about silicon.

    Each bond is covalent with one shared electron from each atom.

    Si has four electrons in its outer energy shell. One each of these electrons combine with the one electron from hydrogen.

    slightly polarized but covalent. the electronegativity difference is the same as in CH4 but the partial charges would be opposite (H is more electronegative). See below for more (for a polar covalent bond the electronegativity difference should be above 0.5, it's less or at most borderline in this case)

    The chemical structure you described meets very closely METHANE's one when Methane is CH4.

    Carbon atom displace its on Valence's Electrons along four equidistant bounds, e.g. Tetrahedron or sp3 Hybridization.

    Any Sigma or C-H Bound exercites its own Dipolar Moment as perfectly counter-balanced by the remaining three you wrote.

    Si and H can form many compounds of varying stability - you are right in that SiH4 is one of them (silane), but you can also have SiH6 (disilane), and different silyl radicals like SiH3 and SiH5. Do you have an equation that you are working with? What are the proportion of your reactants and in what energy context are they being combined?

    it is symmetrical and a non polar compound...therefore electrons are equally shared
