Question

Out of the given compounds, the melting point is maximum for

• A. $LiI$
• B. $LiBr$
• C. $LiF$
• D. $LiCl$

Answer 1

Answer: (C)

$LiF$

With increase in the size of the anion, the polarizability and covalent character increases and the melting point decreases.
Hence, among lithium halides, the melting point of lithium iodide is the lowest and the melting point of lithium fluoride (with the smallest anion) is the highest.
