Question

Specify the co-ordination geometry around and hydridisation of N and B atoms in a 1 : 1 complex of BF3 and NH3.

Solution

Correct option is

N: tetrahedral, sp3; B: tetrahedral, sp3

 

Originally in NH3, N is pyramidal (sp3) and in BF3, B is planar (sp2). But after the bond formation, i.e., in the complex

H3N → BF3, both N and B have four shared pairs of electrons and hence both have tetrahedral (sp3) geometry.
