Question

Oxygen is more electronegative than sulphur. Yet `H_2S` is acidic while `H_2O` is neutral. This is because
A. Water is a highly associated compound
B. Molecular mass of `H_2S` is more than that of `H_2O`
C. `H_2S` is gaseous under ordinary conditions while `H_2O` is a liquid
D. H-S bond is weaker than H-O bond.

Answer 1

Correct Answer - D
`H_2S` is more acidic than `H_2O`. It is due to the fact that H-S bond is weaker than H-O bond.
