Chemistry - CHEMICAL BONDING Question with Solution | TestHub

$120^{\circ }$ Angle: This angle is present in CH₃⁺, CO₃²⁻, and BF₃ (all trigonal planar), as well as in the equatorial positions of XeO₃F₂ (trigonal bipyramidal).

Other Angles: CF₄ is tetrahedral ($109.5^{\circ }$), IF₇ is pentagonal bipyramidal ($72^{\circ }$ and $90^{\circ }$), XeF₂ is linear ($180^{\circ }$), NO₂⁻ is bent ($\approx 115^{\circ }$), and XeO₃ is pyramidal ($\approx 103^{\circ }$).

Since the $120^{\circ }$ angle is the most frequent among the given species, the magnitude is 120.00.
