Question

Which is extremely stable?

• A. $N{{F}_{3}}$
• B. $NC{{l}_{3}}$
• C. $NB{{r}_{3}}$
• D. $N{{H}_{3}}$

Answer 1

Answer: (A)

$N{{F}_{3}}$

Answer 2

Nitrogen form trihalides of the formula $\text{N}{{\text{X}}_{\text{3}}}\text{.}$ Among halides of nitrogen, $\text{N}{{\text{F}}_{3}}$ is extremely stable due to strong N-F bond in $\text{N}{{\text{F}}_{3}}.$ Small size .of both nitrogen and fluorine atom causes strongness of $\text{N}-\text{F}$ bond. $\text{NC}{{\text{l}}_{\text{3}}}$ is explosive yellow oil. $\text{NB}{{\text{r}}_{\text{3}}}$ and $\text{N}{{\text{I}}_{3}}$ are unstable compound and known only as ammonia complex e. , $NB{{r}_{3}}.6N{{H}_{3}}.$
