Among the hydrides of group 16, water shows unusual properties. Why? – InterviewSolution

1.	Among the hydrides of group 16, water shows unusual properties. Why?
Answer» Oxygen being more electronegative, the O-H bond is more polar and there arises association of H₂O molecules through intermolecular hydrogen bonding. The other hydrides of group 16 do not form H bonds and hence exist as discrete molecules. As a result, water shows unusual properties like high B.P, high thermal stability and weaker acidic character as compared to the other hydrides of group 16.
