Question

Specify the co-ordination geometry around and hybridisation of N and B atoms in a 1 : 1 complex of $B{F}_{3}andN{H}_3.$

• A. N is tetrahedral, $s{p}^3$; B is tetrahedral, $s{p}^3$
• B. N is pyramidal, $s{p}^3$; B is pyramidal, $s{p}^3$
• C. N is pyramidal, $s{p}^3$; B is planar, $s{p}^2$
• D. N is pyramidal, $s{p}^3$; B is tetrahedral, $s{p}^3$

Answer 1

The correct option is D N is pyramidal, $s{p}^3$; B is tetrahedral, $s{p}^3$

$H_{3}N:+B{F}_3\to H_{3}N\to B{F}_3$
