Chemistry - CHEMICAL BONDING Question with Solution | TestHub

Question explanation:

Find the correct bond angle order.

Concept: VSEPR theory & Electronegativity

Solution:

Compare H₂O and OF₂ : Both have a central Oxygen atom with sp³ hybridization and 2 lone pairs.

In OF₂ , Fluorine is highly electronegative and pulls the bond pair electrons away from the central oxygen.

This decreases the repulsion between the bond pairs, causing the angle to shrink (≈104.5°)

Note on other options: PH₃ (approx 93°) is much smaller than  PH₄⁺(109.5°).

Final Answer:  OF₂ < H₂O
