13th group or boron group

Question

Which of the following statements is not true

Moderate

A

Boron is a non-metal while all other statements of group-13 are metals
B

Boron tri chloride acts as a Lewis Acid
C

Boron does not form the Hydrated B³⁺ ion
D

The stability of the +1 oxidation state decreases down the group where as +3 increases

Solution

The stability of the +1 oxidation state increases down the group. This is because of the participation of only P-electron . The two S-electrons (S²) do not take part in the chemical reaction (Inert pair effect)
For example TlCl more stable then TlCl₃. Because In TlCl $({Tl}^{+ 1})$ is more stable then ${Tl}^{+ 3}$ due to Inert Pair effect.
