Decreasing order of the hydrogen bonding in following forms of water is correctly represented by
A. Liquid water
B. Ice
C. Impure water

Options

  1. AA=B>CA = B > C
  2. BB>A>CB > A > C
  3. CC>B>AC > B > A
  4. DA>B>CA > B > C

Correct answer

B. B>A>CB > A > C

Step-by-step solution

The extra hydrogen bonds that occur when water freezes increase the space between molecules, causing a decrease in overall density. In fact, each water ice molecule forms hydrogen bonds with four other molecules, while water molecules only form hydrogen bonds with an average of 3.4 other molecules.

Due to impurity extent of H -Bonding decreases.

Ice >> Liquid water >> Impure water
