Question

Which of the following substances has the least ionic character?

• A. $MgC{l}_2$
• B. $AlC{l}_3$
• C. $NaCl$
• D. $LiCl$
• E. $NaF$

Answer 1

Answer: (B)

High charge on cation, anion or both favour covalent character in ionic bond. Hence, $AlC{l}_3$ is maximum covalent in nature and therefore has minimum ionic character.
