Question

Which of the following best describes the molecular orbital theory of bonding? Choose one: A. A theory of bonding based on the mixing of atomic orbitals of similar shapes and energies to form molecular orbitals that extend to two or more atoms B. A theory where the bonds and lone pairs of valence electrons in a molecule are represented in two-dimensions C. A theory that predicts the arrangement of valence electron pairs around a central atom minimizing their mutual repulsion to produce the lowest-energy orientations D. A theory of bonding that describes bonds as the electrostatic attraction between species of opposite charge E. A theory of bonding that assumes covalent bonds form when half-filled orbitals on different atoms overlap or occupy the same region in space

Answer 1

Answer:

A. The molecular orbital theory of bonding is based on the mixing of atomic orbitals of similar shapes and energies to form molecular orbitals that extend to two or more atoms  

Explanation:

When two atoms come close to each other, the waves of their atomic orbitals can interfere constructively or destructively, to form two new molecular orbitals that encompass the whole molecule.

B is wrong. It refers to Lewis structures.

C is wrong. It refers to VSEPR theory.

D is wrong. It refers to ionic bonding.

E. is wrong. It refers to valence bond theory.
