Question

Arrange the acids H₂Se, H₂Te, and H₂S in order of increasing acid strength. A)H₂S < H₂Se < H₂Te B)H₂S < H₂Te < H₂Se C)H₂Te < H₂S < H₂Se D)H₂Se< H₂S < H₂Te E)H₂Se< H₂Te < H₂S

Quizplus · Accepted Answer

The acid strength depends on the electronegativity and size of the central atom. Since selenium is more electronegative than sulfur, H₂Se is stronger than H₂S. Similarly, since tellurium is more electronegative and larger than selenium, H₂Te is stronger than H₂Se. Hence, the correct order of increasing acid strength is H₂S < H₂Se < H₂Te. The answer is choice A.
