B)Boron changes from trigonal planar to tetrahedral geometry during the reaction. C)There are no changes in the formal charge on any atom during the reaction. D)Nitrogen changes from trigonal planar to tetrahedral geometry during the reaction. E)There is no change in geometry around the nitrogen or boron atoms.

The reaction involves the substitution of the leaving group (S1U1B0) in BFS1U1B13S1U1B0 by the NHS1U1B13S1U1B0 group. This leads to the formation of FS1U1B13S1U1B0B-NHS1U1B13S1U1B0. In this reaction, boron changes from trigonal planar to tetrahedral geometry because it forms four bonds instead of three. There are no changes in the formal charge on any atom during the reaction. Nitrogen does not change its geometry.
