Gernanium has an atomic number of 32 while silicon 14. This means GeH4 has more electrons than SiH4, therefore GeH4 has stronger Van der Waals/London forces (types of intermolecular forces) thus modern energy needed to break these forces; higher boiling point.


The boiling point of SiH4 is -112 oC.


SiH4. since it's mass is larger then CH4, London constraints are stronger.


im pritty sure its -111.8


This element is chloroine: -34,04 oC.


Silane has the formula SiH4.


Yes, SiH4 obeys the octet rule


The molar mass of SiH4 is approximately 32.117 grams per mole. So, 9.30 moles of SiH4 has a mass of 298.69 grams.


No, SiH4 is not polar. It is nonpolar. It is considered nonpolar because it does not have permanent dipole moments.


Four covalent Si-H bonds are present in SiH4.

no it is a covalent bond


No (because it is nonpolar).


4.26mol x ( 6.022 x 1023 molecules / 1mol ) = 2.565 x 1024 molecules




Silane, which has the chemical formula SiH4, is a colorless and flammable gas. It is non-polar due to the equal sharing of electrons and the cancellation of the dipole moments.



There is no such compound. Did you mean SiH4 - this is called silane


Yes, when combined with Silicon (Si), as in SiH4.


No. Lewis acids are electron acceptors, forming adducts.


No. SiH4, known as silane, is a nonpolar molecule with polar bonds. Despite containing hydrogen, silane molecules do not feature hydrogen bonding between them because silane is nonpolar, and hydrogen bonding is a particle-level property of polar compounds.


It's nonpolar. It's tetrahedral and the charges are equally distributed.



The chemical equation is:SiH4 = Si + 2 H2
