Chapter 11, Problem 11.25P

Interpretation Introduction

Interpretation:

The two different structures of $\text{2-butene}$ that indicate $\sigma$ and $\pi$ bonds are to be determined.

Concept introduction:

The sigma bond is the covalent bond that is formed by axial or end to end overlap of orbitals. The pi bond is formed by the lateral overlap of orbitals. Both types of bonds can be bonding or anti-bonding interaction. Bonding interaction takes place when there is an overlap of orbitals in the same phase and antibonding interaction occurs when the orbital overlap in opposite phase. Sigma bond is stronger than the pi bond.
