This colorless gas is notable for having a narrow liquid range: its boiling point is only 4 °C above its melting point. It was first prepared in 1771 by Carl Wilhelm Scheele by dissolving silica in hydrofluoric acid , [ 5 ] and later synthesized by John Davy in 1812. [ 6 ]

Silicon tetrafluoride or tetrafluorosilane is a chemical compound with the formula Si F 4. This colorless gas is notable for having a narrow liquid range: its boiling point is only 4 °C above its melting point.
1 ημέρα πριν · In this article, we are going to discuss the chemical bonding of silicon tetrafluoride by understanding its Lewis structure, molecular geometry, and the hybridization of the central atom. Then, we will study the polarity of SiF4 i.e., whether SiF4 is a polar or nonpolar molecule. Contents show.
I can justify that $\ce{SF4}$ has the higher boiling point because it is more polar since its Lewis structure has a lone pair on the sulfur atom, and so it experiences greater dipole-dipole forces. However, why does $\ce{SF4}$ have a lower melting point?
