Question

Back bonding in $B{F}_3$ does not affect:

• A. Planarity, lewis acidic strength and bond angle
• B. Bond length, hybridization and bond strength
• C. Bond angle, planarity and geometry
• D. Lewis acidic strength, bond length and bond order $(B-F)$

Answer 1

The correct option is C Bond angle, planarity and geometry

Due to back bonding in $B{F}_3$, its bond length, bond energy, bond strength and lewis acidic strength changes but there is no change in hybridization, planarity, geometry and bond angle.
