Shapes of certain interhalogen compounds are stated below. Which one of them is not correctly stated? (1) IF7 : pentagonal bipyramid (2) BrF5 : trigonal bipyramid (3) BrF3 : planar T-shaped (4) ICl3 : planar dimeric
- IF7 : pentagonal bipyramid
- BrF5 : trigonal bipyramid
- BrF3 : planar T-shaped
- ICl3 : planar dimeric
Correct answer: BrF3 : planar T-shaped
Solution
BrF3 has a T-shaped geometry due to the presence of three bonding pairs and two lone pairs of electrons, which results in a trigonal bipyramidal arrangement where the lone pairs occupy the equatorial positions, leading to a T-shape.
