To make you understand... Covalent bond strength is roughly correlated with bond order (single < double < triple) because higher order bonds involve a greater amount of electron density between the bonded atoms. Think of electron density as the "glue" that holds the atoms together. In short, because there is more "glue" between the atoms in a double bond, it takes more energy to pull them apart to form the separate atoms compared to a single bond involving the same elements. This explains the observation that the oxygen-oxygen bond in O2 is stronger than the one in H2O2. To write in exam....

In a triple bond, a total of6 electrons are shared. In a double bond, 4 electrons are shared and in a single bond, only 2 electrons are shared. Thus, the bond strength is as follows:
Triple bond > Double bond > Single bond.This means to break all the three bonds in a triple bond, maximum energy is required.
