MCQ
Taking stability as the factor, which one of the following represents correct relationship?
  • ✓
    $TlI > TlI _3$
  • B
    $TlCl _3 > TlCl$
  • C
    $\operatorname{InI}_3 > \ln I$
  • D
    $AlCl > AlCl _3$
✓

Answer

Correct option: A.
$TlI > TlI _3$
a
$T l^{+}$ and $I ^{-}$ > $T l^{+3}$ and $3 I ^{-}$

due to inert pair effect $Tl^{+}$is more stable than $Tl^{+3}$.
