Question

What is the Reactivity order and stability order of single, double and triple bond?

Answer 1

The order of reactivity is as follows

Triple

Double

Single

The way to remember it is that the single bond implies that the molecule is “spent” and therefore unreactive. The double or triple bond implies that the molecule is don't yet spent and can therefore react.

Triple bonds are made of sideways overlapping of p orbitals. This sideways overlapping is weak and can be easily broken by addition reactions. Double bonds have lesser number of pi electrons , relatively more stable than triple bonds.

Stability order is reverse of reactivity order.so stability order is ;
Single >double>triple bond
