Question

Which of the following H-bonds is expected to have maximum strength?

विकल्प

• H-O----H

• H-N----H

• H-S-----H

• All have same strength

Answer 1

H-O----H

Explanation:

Since the strength of H-bonds is correlated with the electro-negativity of the atom connected to hydrogen, O is more electronegative than N and S takes larger strength of H-bonds.
