In organic chemistry, we are often asked to rank the triple, double and single bonds in terms of their strength and length. In a triple bond , 3 pairs of electrons are shared, while in a double bond only 2 pairs are shared and in a single bond, one pair electrons is shared. Therefore it takes more energy to break a triple bond and thus, triple bond is the strongest, followed by the double bond, and single bond. The order of length is opposite of that of strength, the triple bond is the shortest, double bond is in the middle, while the single bond is longest.
