The multiplicity of a C-C bond refers to the number of bonds between two carbon atoms. This can be a single bond, double bond, or triple bond. The s-character of a bond refers to the percentage of the bond's electron cloud that is derived from the s-orbital of the atom.

1. In a single bond (like in alkanes), the bond is sp3 hybridized, meaning it has 25% s-character and 75% p-character.

2. In a double bond (like in alkenes), the bond is sp2 hybridized, meaning it has 33% s-character and 67% p-character.

3. In a triple bond (like in alkynes), the bond is sp hybridized, meaning it has 50% s-character and 50% p-character.

As the s-character increases, the bond length decreases and the bond becomes stronger. This is because s-orbitals are closer to the nucleus and therefore lower in energy than p-orbitals, so a bond with more s-character is lower in energy (more stable) and shorter.

So, as the s-character increases from sp3 to sp2 to sp, the multiplicity of the C-C bond decreases from single to double to triple. This is because a bond with more s-character is stronger and shorter, so it can support more bonds (higher multiplicity).

In conclusion, the multiplicity of a C-C bond decreases with an increase in s-character.
