Identify the correct statement.
A. LiCl has lower melting point than that of NaCl
B. LiCl dissolves more in organic solvents
C. LiCl is more covalent than NaCl
D. LiCl will ionize in water more than NaCl
A and C only
D only
A, B and C only
A, B, C and D
According to Fajan's rules, higher the polarization, higher is the covalent character.
(1) Covalent compound have lower melting point than ionic thus LiCl being more covalent than NaCl has lower melting point than that of NaCl.
(2) Covalent compounds dissolve more in organic non polar solvent than ionic thus LiCl dissolves more in organic solvents.
(3) Due to high polarisation in LiCl, it has more covalent character than NaCl.
(4) Covalent compounds will ionise less than ionic in water. Since LiCl is covalent while NaCl is ionic. As a result, LiCl will not ionize in water more than NaCl.
