Specify the co-ordination geometry around and hybridisation of N and B atoms in a 1:1 complex of B F 3 and N H 3
Options
- AN: tetrahedral, s p 3 ; B : tetrahedral, s p 3
- BN: pyramidal, s p 3 ; B : tetrahedral, s p 3
- CN: pyramidal, s p 3 ; B : planar, s p 2
- DN: pyramidal, s p 3 ; B : pyramidal, s p 3
Correct answer
A. N: tetrahedral, s p 3 ; B : tetrahedral, s p 3
Step-by-step solution
In the 1 : 1 complex H 3 N : → B F 3 , both N and B have s p 3 hybridised and tetrahedral geometry as both N & B atoms have 4 bp electrons .
