Question: $ H_2S $ is more acidic than $ H_2O $ , due to [BVP 2004]

Options:

A) $ O $ is more electronegative than $ S $

B) $ O-H $ bond is stronger than $ S-H $ bond

C) $ O-H $ bond is weaker than $ S-H $ bond

D) None of these

Show Answer

Answer:

Correct Answer: B

Solution:

The acidity of hydrides of VI group elements increase from top to bottom as the bond strength $ X-H $ decrease from top to bottom $ H_2O<H_2S<H_2Se<H_2Te $
