Why nacl3 is not stable while nf3 is stable
Answers
Hey mate your answer!!!!
Despite the similarities of the Pauling electronegativities of nitrogen and chlorine, the NCl3 molecule is very polar with negative charge residing on nitrogen. Theoretical studies indicate that the nitrogen in NCl3 is in the -3 oxidation state and the chlorine atoms in the +1 oxidation state. In contrast, due to the higher electronegativity of fluorine, the N atom of NF3 has a +3
oxidation state and fluorines -1 oxidation state. Halogen in the +1 oxidation state is a good oxidizing agent and it can oxidize the nitrogen to the highly stable N2 and get itself reduced to Cl2 , both stable gases with a release of energy.Therefore NCl3 is explosive. This does not happen in NF3 as the fluorine in -1 state is not an oxidizer and F 2 is not as stable as F- . Size of Cl also matters as three Cl on N is an unstable situation.
Hope it helps to you l!!!!!!!
