which of the following is not one of the conditions of the valence bond theory that results in a covalent bond.

A) covalent bonds form the overlap of atomic orbitals
B) the 2 overlapping lobes of the orbitals must be opposite phase
C) the greater the amount of orbital overlap, the stronger the bond
D) Each of the bonded atoms maintains it's own atomic orbital

Solutions

Expert Solution

The correct answer is option (B).

According to Valence Bond Theory, a covalent bond is formed from the positive overlap of two atomic orbitals.

A positive overlap results when two lobes of the same phase (both positive or both negative) overlap.

An overlap between two lobes of the opposite phase is a negative overlap and does not result in bond formation.

Which of the following statements summarizing valence bond theory is correct? The geometry of the molecule is determined by the geometry of the orbitals used. The orbitals used in bond formation are atomic orbitals (s, p, d, and f). A chemical bond forms only when occupied orbitals are involved. A bond is formed by the overlap of two hybrid orbitals or two atomic orbitals.
