2019年2月11日 · But if the $\ce{Si}$ atom becomes more and more electrophilic, the attack by a water molecule becomes more easier which subsequently results in the increase of the rate of …

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.

2015年5月8日 · Both molecules can theoretically act as a Lewis acid. This would involve the approach of a Lewis base (i.e. a lone pair-carrying group), its interaction with the central atom …

2020年1月8日 · 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 …

2021年7月7日 · 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.

2020年6月14日 · $\begingroup$ @Sanu_012 You don't necessarily have to memorize it I guess. C has got a much greater capacity for catenation as compared to Si, and so the number of …

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 = 48.42 …

After looking for proper reasons for boiling point orders, nobody could even explain why $\ce{CCl4}$ has a higher boiling point than $\ce{SiCl4}$, but after looking for patterns, in lots …
