Question

11 mark for review which of the following molecules has an angular (bent) geometry that is commonly represented as a resonance hybrid of two or more electron - dot structures? a co₂ b o₃ c bef₂ d of₂

Explanation:

1. $CO_2$: It has a linear geometry ($O = C=O$) and no resonance - hybrid with bent geometry.
2. $O_3$: It has an angular (bent) geometry. The ozone molecule can be represented as a resonance hybrid of two electron - dot structures. The central oxygen atom is $sp^2$ hybridized.
3. $BeF_2$: It has a linear geometry ($F - Be - F$) due to the $sp$ hybridization of the beryllium atom.
4. $OF_2$: It has a bent geometry but does not have resonance structures like $O_3$.

Answer:

B. $O_3$
