Select the correct statement (s)

Statement-1 : The melting points of the various fluorides of xenon decrease in the order XeF₂ > XeF₄ > XeF₆.

Statement-2 : Xe – F bond length in XeF2, XeF4 and XeF6 decreases in the order XeF₂ > XeF₄ > XeF₆.

Statement-1 : Ethers behave as bases in the presence of mineral acids.

Statement-2 : It is due to the presence of lone pair of electrons on the oxygen atom.

The elements of group 1 describe, more clearly than any other group of elements, the effects of increasing the size of atoms or ions on the physical and chemical properties. The chemical and physical properties of the elements are closely related to their electronic structures and sizes. These metals are highly electropositive and thus form very strong bases, and have quite stable oxo-salts. In the manufacturing of sodium hydroxide, chlorine and sodium carbonate, the sodium chloride is used as starting material.
