Boiling point of SiCl4 is lower than expected. Its chlorine atoms have higher negative charge due to lower electro negativity of silicon. Therefore the molecules repel each other. this results in lower b.p of SiCl4
SiH4 has a lower boiling point than H2S because SiH4 is a smaller molecule with weaker Van der Waals forces between its molecules compared to the larger H2S molecules, which have stronger Van der Waals forces. The strength of these intermolecular forces influences the boiling points of the substances, with stronger forces requiring more energy to overcome and boil.
The boiling point in degree Celsius are given below:Na: 883K: 774Si: 2355Ne: -246Silicon has the highest boiling point among the elements given.
Silicon Dioxide (Silica) boils at 2230
4.26mol x ( 6.022 x 1023 molecules / 1mol ) = 2.565 x 1024 molecules
In SiH4 (silane), the dominant intermolecular force is London dispersion forces (van der Waals forces) due to the temporary dipoles created by the movement of electrons around the silicon-hydrogen bonds. There are no permanent dipoles in SiH4, so dipole-dipole interactions are negligible.

The compound name for SiH4 is silane. It is a silicon hydride compound that consists of one silicon atom bonded to four hydrogen atoms.
In SiH4 (silane), the dominant intermolecular force is London dispersion forces (van der Waals forces) due to the temporary dipoles created by the movement of electrons around the silicon-hydrogen bonds. There are no permanent dipoles in SiH4, so dipole-dipole interactions are negligible.
The name for the molecular compound SiH4 is silane.
The chemical equation is:SiH4 = Si + 2 H2
No. Lewis acids are electron acceptors, forming adducts.
