Which of the following sequence is correct here?

Question

Which of the following sequence is correct here? (A) Tl < ln < Ga < Al (stability of +1 oxidation state) (B) CO2 < SiO2 < SnO2 < PbO2 (increasing oxidising power) (C) BF3 < BCl3 < BBr3 < Bl3 (the lewis acid strength) (D) Both B and C

Tardigrade Admin · Accepted Answer

Here both B and C are correct but A is incorrect as the correct order is

A l < G a < l n < Tl

(stability of +1 oxidation state)
As due to inert pair effect stability in lower oxidation state increases down the group.

Q. Which of the following sequence is correct here?

$Tl < l n < G a < A l$ (stability of +1 oxidation state)

$C O_{2} < S i O_{2} < S n O_{2} < P b O_{2}$ (increasing oxidising power)

$B F_{3} < BC l_{3} < BB r_{3} < B l_{3}$ (the lewis acid strength)

Both B and C

Here both B and C are correct but A is incorrect as the correct order is
$A l < G a < l n < Tl$ (stability of +1 oxidation state)
As due to inert pair effect stability in lower oxidation state increases down the group.

Tl<ln<Ga<Al (stability of +1 oxidation state)

CO2​<SiO2​<SnO2​<PbO2​ (increasing oxidising power)

BF3​<BCl3​<BBr3​<Bl3​ (the lewis acid strength)

Both B and C

Here both B and C are correct but A is incorrect as the correct order is Al<Ga<ln<Tl (stability of +1 oxidation state) As due to inert pair effect stability in lower oxidation state increases down the group.
