S-1 : The melting point depends on the packing of the molecules. Symmetrical molecules are more closely packed as compared to unsymmetrical molecules. Hence symmetrical molecules will have higher melting points as compared to unsymmetrical molecules.
S-2 : This may be owing to the increase in charge on xenon atom with increasing number of F atoms.

Statement-2: This trend can be explained by the increasing size and decreasing electronegativity of the fluoride ligands as the number of fluorine atoms surrounding the xenon atom increases.
Explanation: The melting point of a compound is influenced by several factors, including the strength of the intermolecular forces between its molecules. In the case of xenon fluorides, these intermolecular forces are predominantly due to London dispersion forces, which arise from fluctuations in the electron distribution within the molecule. As the number of fluorine atoms around the central xenon atom increases, the overall size of the molecule increases, and the distance between the individual molecules also increases. This reduces the strength of the London dispersion forces and makes it easier for the molecules to move past each other, resulting in a lower melting point. Additionally, the electronegativity of the fluorine atoms decreases as their distance from the central xenon atom increases, which also weakens the intermolecular forces and contributes to the decreasing trend in melting points.
