Answer:

In pi bond formation, the correct criterion is the parallel orientation of the two p orbitals on adjacent atoms (option B).

Explanation:

To understand why parallel orientation is necessary for pi bond formation, let's first define what a pi bond is.

A pi bond is a type of covalent bond that occurs when two p orbitals overlap side by side, allowing for the sharing of electron density. It is formed by the sideways overlap of two parallel p orbitals on adjacent atoms.

Here's why option B is the correct answer:

1. Trigonal orientation of the two p orbitals on adjacent atoms (Option A):
Trigonal orientation refers to the arrangement of three atoms in a triangle. While this is a valid arrangement for sigma bond formation (which involves the head-on overlap of atomic orbitals), it is not relevant to pi bond formation. Pi bonds are formed by the sideways overlap of p orbitals, not their trigonal arrangement.

2. Pentagonal orientation of the two p orbitals on adjacent atoms (Option C):
Pentagonal orientation refers to the arrangement of five atoms in a pentagon. Similar to the trigonal orientation, this arrangement is not relevant to pi bond formation. Pi bonds are formed by the sideways overlap of p orbitals, not their pentagonal arrangement.

3. Planar orientation of the two p orbitals on adjacent atoms (Option D):
Planar orientation refers to the arrangement of atoms in a flat plane. While this is a valid arrangement for pi bond formation, it does not specify the correct criterion. The key factor for pi bond formation is the parallel orientation of the p orbitals, not their planar arrangement.

4. Parallel orientation of the two p orbitals on adjacent atoms (Option B):
The parallel orientation of the two p orbitals on adjacent atoms is the correct criterion for pi bond formation. The p orbitals must be aligned in a parallel manner to allow for the sideways overlap, which is necessary for the formation of a pi bond.

In summary, the parallel orientation of the two p orbitals on adjacent atoms is necessary for pi bond formation. This allows for the sideways overlap of the p orbitals, leading to the sharing of electron density and the formation of a pi bond.
