Water on cooling to zero degrees becomes ice. The main reason for this conversion is the hydrogen bonding. Which one of the following statements is correct?

Solution

The correct option is B In ice, the hydrogen bonded H atoms are at longer distance as compared to the other two covalently bounded H atoms around each O atom
Covalent bonds have higher bond energy (ie, they are strong) compared to Hydrogen bondings.
The higher the bond energy, the shorter is the bond length.
Since bond energy of hydrogen-bonded $H$ atom is lesser than covalently bonded $H$ atom, it is at a longer distance from $O$ atom.
Hence, the correct option is B.
