Based on molecular structure, arrange the binary compounds in order of increasing acid strength. explain your choice. h2te hi h2s nah

Weakest NaH < H₂S < H₂Te < HI strongest

NaH is a strong base, it is not acid at all, it ionized to give Na⁺ and H⁻

From up to bottom in periodic table size increases so dissociation of H⁺ becomes easier for larger anions so HI and H₂Te are stronger acids than H₂S

I is more electronegative than Te, So it is easier to lose H⁺ from I than from Te
