Which of the following describes the effect of "Bent's Rule" on the -bond strength in ?
Options:
Answer:
C
Solution:
Question Explanation: Explains how electronegativity affects orbital hybridization and bond strength. Concept: Bent's Rule
Solution: 1. Bent's Rule: "Atomic s-character concentrates in orbitals directed towards electropositive substituents."
2. F is highly electronegative. Therefore, the C orbital directed towards F will have more p-character and less s-character.
3. Increased p-character makes the C−F bond longer/weaker (relatively), while the s-character is redistributed to the C−H bonds, making them shorter and stronger.
Final Answer: Both (A) and (B).
