Why the bond angle H-N-H is 1070 and H-O-H is 1050, instead of 109028’ characteristic of tetrahedral structure?
Lone pair lone pair repulsion in H2O has more magnitude than that of lone pair bond pair repulsion in NH3.

Enumerate the reactions of D-glucose which cannot be explained by its open chain structure.
(1) Aldehydes give 2, 4-DNP test, Schiff’s test, and react with NaHSO4 to form the hydrogen sulphite addition product. However, glucose does not undergo these reactions. (2) The pentaacetate of glucose...

Although the H-bonding in hydrogen fluoride is much stronger than that in water, yet water has a much higher boiling point than hydrogen fluoride.
This is because hydrogen bonding is multidimensional in water whereas in HF it is linear.
