As we learnt that

Isolation Energy of Boron Family -

Does not decreases regularly down the group

- wherein

Discontinuity between Al and Ga, and In and Tl is due to inability of d and f electrons (low screening effect) to compensate the increase in nuclear charge

 

 

 

 

In group 13 the order of atomic radius is not regular due to transition contraction.


Option 1)

B < Ga < Al < Tl < In

This is incorrect.

Option 2)

 B < Al < Ga < In < Tl

This is incorrect.

Option 3)

B < AI < In < Ga < T1

This is incorrect.

Option 4)

 B < Ga < Al < In < Tl

This is correct.
