1.	Which of the following halides of nitrogen is stable?A. `NF_(3)`B. `NI_(3)`C. `NBr_(3)`D. `NCl_(3)`
Answer» Correct Answer - 1 `NF_(3)` behave differently form the others. It is unreactive ,rather like `CF_(4)` and does not hydrolyse with water, dilute acids or alkali. It does react if sparked with water vapour. `2NF_(3)+3H_(2)Orarr6HF+N_(2)O_(3)` The instability of `NCl_(3), NBr_(3)` and `NI_(3)` is because of the weakness of `N-X` bond due to large difference in the size of `N` and `X` atoms. On the other hand ,`N-F` bond is quite strong because the difference is size of `N (75p m)` and `F(72p m)` is small, Consequently ,`NF_(3)` is an exothermic compound which accounts for the stability of `NF_(3)`
