Select the CORRECT order of bond angle in :-

Answer:

B, D

Solution:

PH₃ < AsH₃

PH₃ ≈ 93.5°

AsH₃ ≈ 91.8°

Bond angle decreases with larger central atom → correct order should be PH₃ > AsH₃

CH₄ > H₂O

CH₄ → 109.5° (no lone pairs)

H₂O → 104.5° (2 lone pairs reduce angle)

Correct order

CH₄ > CCl₄

Both tetrahedral ≈ 109.5°

Very slight decrease in CCl₄ due to larger Cl atoms

( incorrect)

109.5° (CCl₄) < 120° (BF₃)
