Question

N2 has one triple bond. CH4 has four single bonds which molecule requires more energy to break the bond wjy

Answer 1

Explanation:

As a nitrogen molecule ($N_{2}$) contains a triple bond between the two nitrogen atoms. Therefore, there is more overlapping taking place as there are two pi bonds and one sigma bond present within a $N_{2}$ molecule.

Hence, in order to break a triple bond high amount of energy is required.

On the other hand, in a $CH_{4}$ all the hydrogen atoms are bonded by a single bond with the hydrogen atom. Hence, there are 4 sigma bonds present in a $CH_{4}$ molecule.

Also, a pi bond is much stronger than a sigma bond.

That is why, $N_{2}$ molecule requires more energy to break the bond.
