Chemical bonds can come in 3 main types, single bonds, double bonds and triple bonds, the difference is, as the name already suggests, the number of bonds that two atoms are forming, this will impact the strength of the bond and also the proximity of both atoms.
The order of strength will be:
1. Triple bonds, they have more bonds and the atoms are closer
2. Double bonds, in between single and triple, they have one extra pi bond which makes it stronger than single bonds
3. Single bonds, only one bond, which makes it weaker than the previous bonds.
For our question:
Single
Double
Triple
