Nitrogen and chlorine have same electronegativity `(3.0)`. Molecular nitrogen is inert at room temperature while chlorine is highly reactive. How will you account for it ?

Text Solution

Verified by Experts

In nitrogen molecule, the atoms are linked by triple bond `(N-=N)` whereas chlorine atoms are linked to each other by single bond `(Cl-Cl)` in chlorine molecule. Due to very high bond dissociation enthalpy` (946 " kJ mol"^(-1))`, molecule nitrogen is very little reactive while molecular chlorine is highly reactive because the bond dissociation enthalpy is very small `(242.6 " kJ mol"^(-1))`.

Why nitrogen is inert at room temperature ?

The electronegativity of nitrogen and chlorine is 3.0 Why nitrogen is inert at room temperature , while chlorine is very reactive?

Although chlorine has the same electronegativity as nitrogen, it does not form hydrogen bonding. Explain.

Both NH_(3) and NF_(3) have identical shapes and same state of hybridisation. Both N-H and N-F bonds have almost the same electronegativity difference. But still, the two molecules have different dipole moment values. How will you account for it ?
