Back bonding in $${ BF } _{ 3 }$$ does not affect :

Aplanarity, Lewis acidic strength and bond angle
Bbond length, hybridisation and bond strength
Cbond length, hybridisation and bond strength
Correct Answer
DLewis acidity, bond length, bond order (B - F).

Solution

π backbonding, also called π backdonation, is a concept from chemistry in which electrons move from an atomic orbital on one atom to an appropriate symmetry antibonding orbital on a π-acceptor ligand. Electrons from the metal are used tobond to the ligand, in the process relieving the metal of excess negative charge. In $$BF_3$$ backbonding occurs and it doesn't change its planarity,bond angle and geometry.
