Draw a picture that shows all three 2p orbitals on one atom and all three 2p orbitals on another atom. (b) How many p bonds can the two sets of 2p orbitals make with each other?

Verified step by step guidance

Step 1: To draw the 2p orbitals, you need to understand that each p orbital is dumbbell-shaped and oriented along one of the three axes (x, y, z). So, for one atom, you will draw three dumbbell-shaped orbitals, each oriented along a different axis. Repeat this for the second atom.

Step 2: Label each of the orbitals as 2px, 2py, and 2pz to indicate their orientation along the x, y, and z axes respectively.

Step 3: To answer part (b), you need to understand that a pi (π) bond is formed by the sideways overlap of two p orbitals. This can happen between the 2px orbitals of the two atoms, the 2py orbitals, and the 2pz orbitals.

Step 4: Therefore, the two sets of 2p orbitals can form up to three pi (π) bonds with each other, one for each pair of overlapping orbitals (2px-2px, 2py-2py, and 2pz-2pz).

Step 5: Keep in mind that this is a theoretical maximum. In reality, the number of pi bonds that can form depends on the specific atoms involved and their electron configurations.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Atomic Orbitals

Atomic orbitals are regions in an atom where there is a high probability of finding electrons. The 2p orbitals are a set of three degenerate orbitals (2px, 2py, 2pz) that can hold a maximum of six electrons. Each orbital has a distinct orientation in space, which is crucial for understanding how atoms bond with each other.

p Bonds

p bonds, or pi bonds, are a type of covalent bond formed when two atomic orbitals overlap laterally. In the case of p orbitals, this occurs when the lobes of the orbitals align side-by-side. Each pair of p orbitals from different atoms can form one p bond, which is essential for the formation of double and triple bonds in molecules.

Orbital Overlap

Orbital overlap is a fundamental concept in chemical bonding that describes how atomic orbitals from different atoms interact to form bonds. The extent of overlap between orbitals determines the strength and type of bond formed. In the context of the question, the overlap of the 2p orbitals from two atoms will dictate how many p bonds can be formed between them.
