In a tabular form. Compare sigma and pi bonds under the following headings Relative strength of each bond type and reactivity of molecules containing each type of bond?

| Bond Type | Relative Strength | Reactivity of Molecules |
|-----------|------------------|------------------------|
| Sigma Bond | Strong | Less Reactive |
| Pi Bond | Weaker | More Reactive |

1. Relative Strength:
- Sigma Bond: Sigma bonds are stronger than pi bonds. They result from the overlap of atomic orbitals along the internuclear axis, allowing for maximum electron density between the bonded atoms.
- Pi Bond: Pi bonds are weaker than sigma bonds. They result from the sideways overlap of p-orbitals, which leads to electron density above and below the internuclear axis.

2. Reactivity of Molecules:
- Sigma Bond: Molecules containing sigma bonds are generally less reactive. Sigma bonds provide strong bonding and stability to molecules, making it more difficult for them to undergo chemical reactions.
- Pi Bond: Molecules containing pi bonds are more reactive. Pi bonds are relatively weaker and more easily broken, allowing for easier chemical reactions and bond rearrangements.

It is important to note that the reactivity of molecules is influenced by various factors, including the presence of other functional groups, electronegativity, and steric effects. The comparison provided above is a general trend and may vary in specific cases.
