Question

The group 13 elements react with halogens to form trihalides except (A) BCl 3 (B) TlI 3 (C) AlCl 3 (D) GaI 3

Tardigrade Admin · Accepted Answer

The elements of group 13 react with halogens to form trihalides (except TlI 3 ). Tl forms TlI instead of TlI 3. The reaction is given below: 2 E(s)+3 X2(g) longrightarrow 2 E X3(s) [X= F , Cl , Br , I ]

Q. The group $13$ elements react with halogens to form trihalides except

$Tl I_{3}$

$A lC l_{3}$

$G a I_{3}$

The elements of group $13$ react with halogens to form trihalides (except $Tl I_{3}$ ). $Tl$ forms $Tl I$ instead of $Tl I_{3}$ .
The reaction is given below :
$2 E (s) + 3 X_{2} (g) ⟶ 2 E X_{3} (s) [X = F, Cl, B r, I]$
