Contrast sigma bonds and pi bonds.
Understand the Problem
The question is asking for a comparison between sigma bonds and pi bonds, which are both types of covalent bonds in chemistry. It seeks to clarify their differences in terms of formation, strength, and characteristics.
Answer
Sigma bonds are stronger and formed head-on; pi bonds are weaker and formed side-to-side.
Sigma bonds are stronger and formed by head-on overlap of orbitals, while pi bonds are weaker and formed by side-to-side overlap of p orbitals.
Answer for screen readers
Sigma bonds are stronger and formed by head-on overlap of orbitals, while pi bonds are weaker and formed by side-to-side overlap of p orbitals.
More Information
Sigma bonds allow for free rotation around the bond axis, making them more flexible in molecular structures. Pi bonds restrict rotational freedom, contributing to the rigidity of molecular shapes.
Tips
A common mistake is to confuse the orientation of orbital overlap in sigma and pi bonds. Remember, sigma bonds are head-on while pi bonds are side-to-side.
