inorganic chemistry - Rate of hydrolysis of silicon tetrahalides ...
Feb 11, 2019 · We can justify the rate of hydrolysis of Silicon tetrahalides if we just think on the statement carefully. The statement claims that the rate of hydrolysis is in the order $\ce {SiF4 > SiCl4 …
Strength of intermolecular force between SiH4 and CH4 molecules
May 31, 2025 · SiH4 and CH4 The only intermolecular force they both have is London Dispersion forces Strength of LDF is determined by molar mass molar mass of SiH4 = 32.132 molar mass of CH4 = …
intermolecular forces - Why does silicon tetrafluoride have a higher ...
So looking at the Wikipedia pages of sulfur tetrafluoride and silicon tetrafluoride, the melting points are −121 °C and −90 °C respectively, and so $\\ce{SiF4}$ has the higher melting point. However,
Why is boiling point of carbon tetrachloride greater than silicon ...
Jun 4, 2020 · $\\ce{CCl4}$ and $\\ce{SiCl4}$ both are non polar molecules thus London forces must be the only forces of interaction. Then London forces are supposed to be greater in $\\ce{SiCl4}$ due to …
Comparing the Lewis acidity of carbon tetrafluoride and silicon ...
Mar 20, 2017 · I've been asked to compare the relative acidity of $\\ce{CF4}$ and $\\ce{SiF4}$. As both atoms have noble gas configurations, neither can act as a lewis acid and so I assume the question is …
Why does SiH4 have unusually large bond angles?
Jan 8, 2020 · The geometry depends on the nature of the doublets around the central atom. If the doublets are all bonding, like in $\ce {CH4},$ $\ce {SiH4}$ and $\ce {GeH4},$ the geometry of the …
ionic compounds - In a crystal of NaCl, how are the NaCl molecules ...
May 3, 2024 · Huh, this question arguably isn't as lame as it looks. It's surprising you'd think there are discrete molecules of NaCl in crystal lattice, but they are in NaCl vapor. They turn into oligomers and …
inorganic chemistry - Towards a hard Lewis base like water which is the ...
Jul 7, 2021 · On Pauling scale, both $\ce {Si}$ and $\ce {Sn}$ have electronegativity value of $\mathrm {1.9}$. The difference is in size of d-orbitals which accept lone pair of electrons. $\ce {Si}$ has …
inorganic chemistry - Is silicon dioxide decomposition possible ...
May 15, 2020 · I was thinking about this, I made Gibbs free energy calculations and I can't figure out if $$\\ce{SiO2(s) -> Si(s) + O2(g)}$$ is actually possible, even at a ridiculous high temperature.
Is iodine violet or purple in colour? - Chemistry Stack Exchange
Dec 2, 2025 · Iodine is often described to be violet or purple in colour. These two terms are used quite interchangeably. Yet it is common knowledge that violet is a spectral colour, while purple is a mix of …
