Molecular nitrogen is very inert chemically. Why ?

Text Solution

Verified by Experts

Nitrogen molecule is diatomic and the two nitrogen atoms are linked by triple bond `(N-=N)`. As the bond dissociation enthalpy is very high `(946 " kJ mol"^(-1))`, it is not possible to cleave the triple bond so easily. Therefore, molecular nitrogen is very inert chemically.
