2024年6月8日 · SIF4 is a molecular compound because it consists of covalent bonds between silicon and fluorine atoms. Ionic compounds involve the transfer of electrons between a metal and a non-metal.

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, their boiling points are −38 °C and −86 °C, respectively, giving $\ce{SF4}$ the higher boiling point.

2024年6月6日 · SiF4 bond type? :Structure of SiF4 is a regular tetrahedron, any regular geometry has net zero dipole moment as all individual dipole in a molecule cancel the effect of each other.

2024年6月18日 · SiF4 is a covalent molecule. The rule that a bond is ionic if the difference in electronegativities is >1.7 is only a rule-of-thumb. It has a low melting point etc. and all the characteristics ...

2024年6月6日 · The oxidation number of silicon (Si) in SiF4 is +4. This is because each fluorine atom in the compound has an oxidation number of -1, and since SiF4 is a neutral compound, the oxidation numbers ...

2024年6月1日 · SiF4 is not ionic; it is a covalent compound. The bonding in SiF4 involves the sharing of electrons between silicon and fluorine atoms, which results in a stable electron configuration for both atoms.

2024年5月31日 · SiF4 bond type? :Structure of SiF4 is a regular tetrahedron, any regular geometry has net zero dipole moment as all individual dipole in a molecule cancel the effect of each other.

SiF4 is a covalent molecule. The rule that a bond is ionic if the difference in electronegativities is >1.7 is only a rule-of-thumb. It has a low melting point etc. and all the characteristics ...

2019年2月11日 · So, by thermodynamic consideration also, rate of hydrolysis should be, $\ce{SiF4 > SiCl4 > SiBr4 > SiI4}$. Lastly, the $\pi$-bonding is not important in case of large size difference between $\ce{Si}$ and $\ce{F}$ ($2p$ and $3d$ have course greater size difference though you may not admit). The fluorine atom makes the silicon more electrophilic ...

2024年5月20日 · SiF4 is not polar as the fluorines negative dipoles cancel each other out as the are all pulling away form the centre equally (the centre being silicon which has a lower electronegativity than ...
