Current Question (ID: 21212)

Question:

$\text{Given below are two statements:}$ $\text{Statement I:}$ $\text{The stability of } +1 \text{ oxidation state increases down the group in Group-13.}$ $\text{Statement II:}$ $\text{The atomic radius of } Ga \text{ is greater than that of } Al.$

Options:

1. $\text{Statement I is incorrect but Statement II is correct.}$
2. $\text{Both Statement I and Statement II are incorrect.}$
3. $\text{Both Statement I and Statement II are correct.}$
4. $\text{Statement I is correct but Statement II is incorrect.}$

Solution:

$\text{Hint: Inert Pair effect}$ $\text{S-1: Stability of } +1 \text{ oxidation state increases down the group due to inert pair effect } \Rightarrow \text{ S-1 is true}$ $\text{S-2: Radius of } Ga \text{ is smaller than } Al \text{ due to d-block contraction } \Rightarrow \text{ S-2 is false}$
