Answer to Question #93118 in General Chemistry for Nduduzo

Question

Which theory is useful to determine geometrical structure of molecules?
A. Resonance theory
B. VSEPR theory
C. Molecular orbital theory
D. Quantum mechanics

Answer 1

Resonance theory: It deals with conjugated bonds where in the single structure can't define the actual structure of molecule and hence combination of several distinct structures are used.

VSEPR Theory: Valence Shell electron pair repulsion theory is used to know the structure of molecules by placing the electrons as far as possible and hence minimizing the repulsion.

Molecular Theory: It deals with the electronic structure of molecules using quantum mechanics.

Quantum Theory : It deals with the nature of particles at subatomic level.

Thus The correct answer is VSEPR Theory.
