Question

Which of the following element can be involved in pπ-pπ bonding?

• A. hydrogen
• B. lithium
• C. carbon
• D. beryllium

Answer 1

Answer:

C. carbon

• Carbon's p Orbitals: Carbon has p orbitals available for bonding.

• Sideways Overlap: p orbitals overlap sideways to form pi (π) bonds.

• pπ-pπ Bond: Sideways overlap of p orbitals on two atoms.

• Double/Triple Bonds: Contain pπ-pπ bonds (the π part).

• Aromatic Rings: pπ-pπ bonding creates delocalized electron systems.

• Key Idea: This type of bonding is crucial for many carbon-containing molecules.
