Choose the correct answer from the options given below:
Decreasing order of the hydrogen bonding in following forms of water is correctly represented by
A. Liquid water
B. Ice
C. Impure water
Choose the correct answer from the options given below:
- $C >B >A$
- $B > A >C$
- $A=B >C$
- $A >B> C$
The Correct Option is B
Solution and Explanation
Hydrogen bonding in water is influenced by the structural arrangement and the presence of impurities:
- Ice: In ice, water molecules are arranged in a crystalline structure with extensive hydrogen bonding. This fixed arrangement allows for maximum hydrogen bonding, making ice have the strongest hydrogen bonding among the three forms.
- Liquid Water: In liquid water, hydrogen bonds are dynamic and constantly break and reform due to molecular motion. This results in slightly weaker hydrogen bonding compared to ice.
- Impure Water: Impurities in water disrupt the hydrogen bonding network, further weakening the hydrogen bonding compared to pure liquid water.
Conclusion: The decreasing order of hydrogen bonding is: \[ \text{Ice (B) $>$ Liquid Water (A) $>$ Impure Water (C)} \]

Concepts Used:
Chemical Bonding and Molecular Structure
Such a group of atoms is called a molecule. Obviously, there must be some force that holds these constituent atoms together in the molecules. The attractive force which holds various constituents (atoms, ions, etc.) together in different chemical species is called a chemical bond.
Types of Chemical Bonds:
There are 4 types of chemical bonds which are formed by atoms or molecules to yield compounds.
- Ionic Bonds - Ionic bonding is a type of chemical bonding which involves a transfer of electrons from one atom or molecule to another.
- Covalent Bonds - Compounds that contain carbon commonly exhibit this type of chemical bonding.
- Hydrogen Bonds - It is a type of polar covalent bonding between oxygen and hydrogen wherein the hydrogen develops a partial positive charge
- Polar Bonds - In Polar Covalent chemical bonding, electrons are shared unequally since the more electronegative atom pulls the electron pair closer to itself and away from the less electronegative atom.
Factors Affecting Bond Enthalpy in Chemical Bonding:
- Size of the Atom
- Multiplicity of Bonds
- Number of Lone Pair of Electrons Present
- Bond Angle
