MCQ
In ice, the length of $H-$ bonds
  • A
    is less than that of covalent bonds
  • ✓
    is greater than that of covalent bonds
  • C
    is same as that of covalent bonds
  • D
    can be less greater or same as that of covalent bonds
✓

Answer

Correct option: B.
is greater than that of covalent bonds
b
The length of $H$ bonds is greater than covalent bonds because as covalent bond there is within molecule and attraction makes atom closer while in $H$ bonding is with neighbour atom and due to repulsion between center atom makes molecule apart that's why $H$ bond length is greater.
