Which of the following is a positive overlap that leads to bonding? (I) (II) (III) (IV)
Options
- AI and II
- BII and III
- CIII and IV
- DI and IV
Correct answer
B. II and III
Step-by-step solution
Concept: Overlapping of only same phase creates bonding. (I) There is no case of bonding as a positive phase cannot simultaneously make bond with other orbital's positive as well as negative phase (II) This creates bonding of p and d orbital. (III) This creates bonding of two 'p' orbitals. (IV) This is the case of anti-bonding of two 'd' orbitals.
