A) co-ordinate bonding
B) convalent 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 \[{{H}_{2}}O\] molecule is covalently linked with two \[H-\]toms of its own molecule and with another \[H-\]atom of adjacent \[{{H}_{2}}O\] molecule by H-bonding. \[H-\underset{\begin{smallmatrix} | \\ H \end{smallmatrix}}{\mathop{O}}\,---H-\underset{\begin{smallmatrix} | \\ H \end{smallmatrix}}{\mathop{O}}\,---H-\underset{\begin{smallmatrix} | \\ H \end{smallmatrix}}{\mathop{O}}\,---H-\underset{\begin{smallmatrix} | \\ H \end{smallmatrix}}{\mathop{O}}\,-\] \[H-\]bonding in water molecules
