A) co-ordinate bonding
B) covalent bond
C) electrostatic force of attraction
D) hydrogen bonding
Correct Answer: D
Solution :
The higher boiling point of water is due to hydrogen bonding. Each O-atom of each \[{{\text{H}}_{\text{2}}}\text{O}\] molecule is covalently linked with two H- atoms of its own molecule and with another H-atom of adjacent \[{{\text{H}}_{\text{2}}}\text{O}\] molecule by H-bonding. \[\underset{\text{H}-\text{bondig}\,\text{in}\,\text{water}\,\text{moleules}}{\mathop{H-\underset{H}{\mathop{\underset{|}{\mathop{O}}\,}}\,---H-\underset{H}{\mathop{\underset{|}{\mathop{O}}\,}}\,---H-\underset{H}{\mathop{\underset{|}{\mathop{O}}\,}}\,---H-\underset{H}{\mathop{\underset{|}{\mathop{O}}\,}}\,-}}\,\]You need to login to perform this action.
