Nettet4. jun. 2024 · $\ce{CCl4}$ 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 its larger size and its boiling point should be higher than comparatively smaller $\ce{CCl4},$ but $\ce{CCl4}$ has higher boiling point..

Nettet6. jun. 2016 · 1. 0. SiCl4 is not ionic, therefore it does not have free electrons to conduct electricity when in molten state. However, when SiCl4 reacts with water, it form SiO2 and HCl. SiO2 is insoluble in water, but HCl conducts electricity since it's ionic. Source from my school notes :D. Post reply.
