Chemical Bonding And Molecular Structure Question 528

Question: Bond angle between two hybrid orbitals is $ 105^{o}.% $ s-orbital character of hybrid orbital is

Options:

A) Between $ 20-21% $

B) Between $ 19-20% $

C) Between $ 21-22% $

D) Between $ 22-23% $

Show Answer

Answer:

Correct Answer: D

Solution:

Bond angle between two hybrid orbitals is $ 105^{o} $ it means orbitals are $ sp^{3} $ hybridised but to lone pair repulsion bond angle get changed from $ 109^{o} $ to $ 105^{o} $ . So its % of s-character is between 22-23%.
