According to VESPR Model the geometry of molecule having 5 bond pair in outer most shell will be __________________?
Correct answer: C. Trigonal bipyramidal
- A. Triangular
- B. Square planner
- C. Trigonal bipyramidal
- D. Octahedral
Explanation
Five bonding electron pairs around a central atom arrange themselves as far apart as possible in a trigonal bipyramidal electron geometry, with three equatorial and two axial positions. Therefore, option c is correct. The likely mistake is choosing d because octahedral geometry also has several electron pairs, but it requires six electron domains.

About VSEPR Theory
Valence shell electron pair repulsion theory predicts molecular shape by arranging bonding pairs and lone pairs around a central atom to minimize repulsion. Questions cover linear, trigonal planar, tetrahedral, trigonal bipyramidal and octahedral electron geometries, bond angles and distortions caused by lone pairs. Electron geometry is not always the same as molecular shape.
