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 $1.8.$
