MCQ
The following salt shows maximum covalent character
  • ✓
    $AlC{l_3}$
  • B
    $MgC{l_2}$
  • C
    $CsCl$
  • D
    $LaC{l_3}$
✓

Answer

Correct option: A.
$AlC{l_3}$
(a) Among the given choice $Al$ is least electropositive therefore, the bond between $Al$ and $Cl$ will be least ionic or most covalent or the difference in electronegativeity of two atom is less than $1.8.$
