VSEPR Theory and Molecular Geometry
Valence Shell Electron Pair Repulsion (VSEPR) theory predicts molecular shapes based on electron pair repulsions around the central atom.
Why this shows up in the exam
NEET and JEE frequently ask you to determine molecular geometry, bond angles, and identify isostructural species.
How NEET tests this
Practise it
These are real questions from past NEET papers that test this exact idea.
Which of the following molecules does not have a linear arrangement of atoms?

Molecular Orbital Theory
Molecular Orbital (MO) Theory explains bonding in molecules by combining atomic orbitals to form molecular orbitals, predicting bond order, magnetism, and stability.
Hybridization and Molecular Shape
Hybridization describes the mixing of atomic orbitals to form new hybrid orbitals, determining molecular geometry and bond angles.
Isoelectronic and Isostructural Species
Isoelectronic species have the same number of electrons, while isostructural species share the same molecular geometry.
Bond Length, Bond Order, and Related Properties
Bond order indicates the number of chemical bonds between a pair of atoms, influencing bond length, strength, and stability.
Sigma and Pi Bonds
Sigma (σ) and pi (π) bonds are types of covalent bonds formed by different orbital overlaps, affecting molecular structure and reactivity.
Molecular Polarity and Dipole Moment
Molecular polarity arises from differences in electronegativity and molecular geometry, quantified by the dipole moment.
