The tendency to show inert pair effect follows the order :
$G a < A l < I n < T l < B$
$B < A l < G a < I n < T l$
$B = A l = G a < I n < T l$
$T l < I n < G a < A l < B$

Question

The tendency to show inert pair effect follows the order -Ga- Al- In- Tl- BB- Al- Ga- In- TlB-Al-Ga- In- TlTl- In- Ga- Al- B

Toppr Admin · Accepted Answer

Down the group inert pair effect increases so the correct order is B-lt-Al-lt-Ga-lt-In-lt-Tl-

The tendency to show inert pair effect follows the order :Ga<Al<In<Tl<BB<Al<Ga<In<TlB=Al=Ga<In<TlTl<In<Ga<Al<B
