हिन्दीTaking stability as the factor, which one of the following represents correct relationship?
Correct answer · Option 2
\( \text{TlI} > \text{TlI}_3 \)
Explanation
Due to the inert pair effect, the lower oxidation state (+1) becomes more stable for heavier elements in group 13. Hence, Tl(I) is more stable than Tl(III), making \( \text{TlI} > \text{TlI}_3 \).
