A) \[C{{O}_{2}}\]
B) \[{{H}_{2}}O\]
C) \[S{{O}_{2}}\]
D) \[N{{O}_{2}}\]
Correct Answer: B
Solution :
All the molecules have O atom with lone pairs, but in \[{{\text{H}}_{\text{2}}}\text{O}\] the H atom has no vacant orbital for \[\pi \] bonding. That's why it does not have any \[\pi \] bond. |
In all other given molecules, the central atom because of the presence of vacant orbitals is capable to farm \[\pi \] bonds. |
