Question

The stability of +1 oxidation state in group-13 increases down the grroup. Why ?
Don't SPam (⋋▂⋌)​​

Answer 1

1 Answer. In group 13 and 14, as we move down the group, the tendency of s-electrons of the valence shell to participate in bond formation decreases. ... Hence, +1 and +2 oxidation states, in group 13 and 14 respectively, become -more stable with increasing atomic number

Answer 2

Answer:

As we go down the group, the stability of +1 oxidation state in group 13 increases.

Due to inner pair effect. And effective nuclear charge.
