Chemical Bonding And Molecular Structure Question 307
Question: Specify the coordination geometry around and hybridization Of N and B atoms in a 1 : 1 complex of $ BF_3 $ and $ NH_3 $ :
Options:
A) N: tetrahedral, $ sp^{3} $ , B: tetrahedral, $ sp^{3} $
B) N: pyramidal, $ sp^{3} $ ‘, B: pyramidal, $ sp^{3} $
C) N: pyramidal, $ sp^{3} $ , B: planar, $ sp^{2} $
D) N: pyramidal, $ sp^{3} $ , B: tetrahedral, $ sp^{3} $
Show Answer
Answer:
Correct Answer: A
Solution:
- The 1: 1 complex both $ BF_3 $ and $ NH_3 $ is represented as follows: in this complex both N and B attain tetrahedral geometry and $ sp^{3} $ hybridization in the coordinately formed structure. During coordinate bond formation hybridized state of donor doesn-t change but hybridized state of acceptor changes.
