Highly selective Backlog Qs for JEE MainChemistryChemical Bonding and Molecular Structure
Which of the following statements is incorrect?
Options
- AH e 2 does not exist because its bond order is zero.
- BO 2 , O 2 - and O 2 + are all paramagnetic.
- CAny two atomic orbitals can combine to form two molecular orbitals.
- Dπ ( 2 p x ) and π ( 2 p y ) are degenerate molecular orbitals
Correct answer
C. Any two atomic orbitals can combine to form two molecular orbitals.
Step-by-step solution
Only those atomic orbitals, that have equal or nearly equal energy combine to form molecular orbitals. This is because these orbitals have zero or less energy gap between them, which helps to provide them better overlapping. Hence, they form stable bonds.
