Which one of the following molecules contain no -bond?

Options

  1. ACO ₂
  2. BH ₂ O
  3. CSO ₂
  4. DNO ₂

Correct answer

B. H ₂ O

Step-by-step solution

All the molecules have O atom with lone pairs, but in H ₂ O the H atom has no vacant orbital for bonding. That's why it does not have any bond. In all other given molecules, the central atom because of the presence of vacant orbitals is capable to farm bonds.
