The bond angle in is
Options:
Answer:
A
Solution:
Explain the question:
Compare bond angle of PH3 with NH3 .
Concept:
Effect of lone pair and hybridisation.
Solution:
• In NH₃ , nitrogen is sp³ hybridised with strong lone pair–bond pair repulsion, giving bond angle 107° .
• In PH₃ , phosphorus shows almost no hybridisation according to drago's rule and lone pair is less effective.
that's why H–P–H bond angle is about 93.5° , much smaller than NH₃.
Final Answer: Final Answer: Option (A)
