Question

HI or H2Te comparing strongest acid,

so since HI is only one H attached to iodine (binary)

don't i need to compare with atomic sizes I vs Te?

why do i have to look at electron negativity which then HI is stronger?..

i only compare electro negativity if there is a presence of oxygen no?

Answer 1

Ans :- HI is the strongest acid than H₂Te.

Explanation :-

H-I bond is more polar as compare to H-Te ,as Iodine i.e I ( group 17 member i.e halogen family ) is more electronegative than Te (group 16 elements i.e oxygen family) because electronegativity increases left to right in periodic table. due to the more polarity of H-I bond the release of H⁺ in HI become much easier. Hence HI will be the stronger Acid than H₂Te.

Note :- Stronger acid will release H⁺ more easily.
