Why SiCl4 react with water but CCl4 does not?

The difference is mostly due to the atomic size of C and Si. Smaller С atom is completely blocked off by four bulky chlorine atoms, so the water molecule can’t reach it. Larger Si is easier to attack.

Why CCl4 is more stable than SiCl4?

ccl4 has a higher boiling point than sicl4 due to the comparatively higher electronegativity difference between c and cl than Si and Cl the c-cl bond is more polar than Si-cl which results in strong intermolecular force of attraction and is thus more hard to break and has relatively more boiling point.

Why CCl4 is insoluble in water but SiCl4 is soluble in water?

CCl4 is highly non polar molecule. So it doesnot dissolve in water. SiCl4 is a polar molecule. So it is dissolved in water.

Why does SiCl4 react with water?

The oxygen atom can therefore bond to silicon before a silicon-chlorine bond breaks, makes the whole process easier energetically. In practice, silicon tetrachloride therefore reacts violently with water, forming white solid silicon dioxide and HCl gas.

Why is CCl4 unreactive with water?

Carbon tetrachloride has no reaction with water. The reaction would have to start by the water molecule’s oxygen attaching itself to the carbon atom via the oxygen’s lone pair. A chlorine atom would get pushed off the carbon in the process.

Why CCl4 is inert towards hydrolysis?

CCl4 is not readily hydrolysed due to non-availability of d-orbital in carbon.

Which among CCl4 & SiCl4 is more easily Hydrolysable and why?

CCl4 doesn’t undergo hydrolysis because of the absence of vacant d-orbitals. But in SiCl4 silicon has vacant d-orbitals which can be used for hydrolysis. Hence SiCl4 can undergo hydrolysis.

Why is CCl4 not soluble in water?

Carbon tetrachloride CCl4 is insoluble in water due to absence of hydrogen atom that can form hydrogen bonding with water.

How does CCl4 react with water?

Carbon tetrachloride has no reaction with water. If you add it to water, it simply forms a separate layer underneath the layer of water. The reaction would have to start by the water molecule’s oxygen attaching itself to the carbon atom via the oxygen’s lone pair.

Why does CCl4 not dissolve in water?

What is the difference between CCl4 and SiCl4?

Ccl4 is small in size due to its small in size it has stronger bonds than sicl4 so it requires more energy to break bonds and also sicl4 has greater hybridisation due to which it has greater bond length which is weak when compared to bonds in ccl4

Why doesn’t SiCl4 dissolve in water?

S i C l X 4 does not quite dissolve in water; rather, it reacts with water. So does C C l X 4, albeit extremely slowly, so for most purposes one may safely assume it doesn’t. The difference is mostly due to the atomic size of C and Si. Smaller С atom is completely blocked off by four bulky chlorine atoms, so the water molecule can’t reach it.

Why is Si-Cl more polar than si-co2?

Smaller С atom is completely blocked off by four bulky chlorine atoms, so the water molecule can’t reach it. Larger Si is easier to attack. Another factor is that silicon is a less electronegative element than carbon, so that the Si-Cl bonds will have more polar character.

What happens when silicon tetrachloride reacts with water?

A silicon tetrachloride reacts with water, while carbon tetrachloride does not. This is due to the fact that the carbon does not have d-orbitals to accept lone pair of electron from water, while silicon has vacant d-orbitals to accept lone pair of electron from water.
