MCQ
Taking stability as the factor, which one of the following represents correct relationship?
- A$AlCl _3< AlCl$
- B$TlCl 3> TICl$
- C$TlI _3> TlI$
- ✓$AlCl < AlCl _3$
✓
Answer
Correct option: D.
$AlCl < AlCl _3$
(D)
Going down the group 13, stability of lower oxidation state increase.
In case of B, Al, Ga and In , higher O.S. +3 remains more stable than lower O.S. +1 .
But in last stable element, thallium (TI), lower O.S. +1 become more stable tahn higher O.S. +3 .
