Chemical Bonding And Molecular Structure Question 542
Question: The bond angle in ammonia molecule is [EAMCET 1980]
Options:
A) $ 91^{o}{8}’ $
B) $ 93^{o}3’ $
C) $ 106^{o}45’ $
D) $ 109^{o}28’ $
Show Answer
Answer:
Correct Answer: C
Solution:
In $ NH_3,sp^{3} $ -hybridization is present but bond angle is $ 106^{o}4{5}’ $ because Nitrogen has lone pair of electron according to VSEPR theory due to bp-lp repulsion bond angle decreases from $ 109^{o}45’ $ to $ 106^{o}4{5}’ $ .
