The dipole moment (𝜇) of BrF is 1.42 D and the bond length is 176 pm. The atomic charge distribution (𝑞) in the molecule
The principle of molecular bonding explains that hybridization and orbital overlap dictate geometry and reactivity. Hence Option NAT fits best because it satisfies bonding and stability criteria, as documented in authoritative sources on chemistry.
