Question

15. Which of the following statements is correct for 1 : 1 complex of (CH3)2N and BF3 1) Geometry around Nis pyramidal with sp3 hybridisation and that around B is planar with sp2 hybridisation
2) The B-F bond length in the complex is longer than that in BF3
3) The geometry around N and B both are tetrahedral with sp3 hybridisation
4) 2 and 3 both

Answer 1

Answer:

No doubt NH

3

and BF

3

have sp

3

(pyramidal) and sp

2

(coplanar) hybridization, respectively, having one lone pair of electron on N atom which is responsible for pyramidal shape of NH

3

in spite of sp

3

-hybridization. However, as soon as it is coordinated to BF

3

, both attain tetrahedral geometry and acquire sp

3

hybridization.
