Oxygen is more electrnegative than sulphur, yet H₂S is acidic in nature while H₂O is neutral, because
Options
(a) H₂O molecule are associated due to intermolecular hydrogen bonding
(b) H₂O has higher oiling point than H₂S
(c) H–S is weaker than O–H bond
(d) H₂S is gas while H₂O is liquid at ordinary temperature.
Correct Answer:
H–S is weaker than O–H bond
Explanation:
On moving down the group, acidity or stability of bond is not decided by electronegativity differences. Change in size is more significant. As the size of bonded atoms become gradually incomparable, stability of bond decreases.
