Explain the following-AlF-3- is a high melting solid whereas SiF-4- is a gas-

Question

Toppr Admin · Accepted Answer

-AlF-3- is an ionic solid due to large difference in electronegativities of -Al- and -F- whereas -SiF-4- is a covalent compound and hence there are only weak van der Waal-s forces among their molecules-

Explain the following:
$$AlF_{3}$$ is a high melting solid whereas $$SiF_{4}$$ is a gas.

$$AlF_{3}$$ is an ionic solid due to large difference in electronegativities of $$Al$$ and $$F$$ whereas $$SiF_{4}$$ is a covalent compound and hence there are only weak van der Waal's forces among their molecules.
