The correct Answer is:
To determine the strength of bonds formed by overlapping atomic orbitals, we can analyze the types of overlaps: SS, SP, and PP. The strength of these bonds is influenced by the percentage of S-character in the hybridization of the orbitals involved. ### Step-by-Step Solution: 1. **Understanding Orbital Overlaps**: - **SS Overlap**: This occurs when two s orbitals overlap. Since s orbitals have 100% s-character, this type of bond is expected to be the strongest. - **SP Overlap**: This occurs when one s orbital overlaps with one p orbital. The hybridization here has 50% s-character and 50% p-character, making it stronger than the PP overlap but weaker than the SS overlap. - **PP Overlap**: This occurs when two p orbitals overlap. Since p orbitals have 0% s-character, this bond is the weakest among the three. 2. **Ranking the Bond Strengths**: - Based on the percentage of s-character: - SS overlap has 100% s-character (strongest). - SP overlap has 50% s-character (intermediate strength). - PP overlap has 0% s-character (weakest). - Therefore, the order of bond strength from strongest to weakest is: **SS > SP > PP**. 3. **Conclusion**: - The final order of bond strength based on the overlapping of atomic orbitals is: - **SS > SP > PP**.

Overlap Of Atomic Orbitals

According to VBT any covalent bond will be formed by overlapping of atomic orbitals of bonded atoms provided atomic orbitals must be half-filled and electrons be in opposite spin. According to type of overlapping covalent bonds can be classified as (a) sigma -bond (b) pi -bond (c ) delta -bond : The combination of orbital that can not produce non-bonding molecular orbital is (internuclear axis is z-axis ) :
