Hydrogen bonding between Ha nd F atom is stronger than that between H and O atoms. However, H_(2)O is more viscus and its bp is greater than that of HF. Explain.

Hydrogen bonding between Ha nd F atom is stronger than that between H

1.	Hydrogen bonding between Ha nd F atom is stronger than that between H and O atoms. However, H_(2)O is more viscus and its bp is greater than that of HF. Explain.
Answer» Solution :Hydrogen bonding between H----F is much stronger than that between H----O because F is more ELECTRONEGATIVE than O. however boiling point of `H_(2)O` is much higher than that of HF because a single molecule of water can form four H-bonds with four other `H_(2)O` molecules, while one `H-F` molecule can form only two H-bonds with four other `H_(2)O` molecules, while one H-F molecule CANN form only two H-bonds with HF molecules. Because of this, `H_(2)O` is more VISCUS thann HF and its boiling point is higher.
