Taking stability as the factor, which one of the following represents correct relationship?
A
$TlI > TlI _3$
B
$TlCl _3 > TlCl$
C
$\operatorname{InI}_3 > \ln I$
D
$AlCl > AlCl _3$
(NEET-2023)
Solution
$T l^{+}$ and $I ^{-}$ > $T l^{+3}$ and $3 I ^{-}$
due to inert pair effect $Tl^{+}$is more stable than $Tl^{+3}$.
