Question

With excess of $C{l}_2$, ammonia forms :

• A. ammonium chloride
• B. nitrogen trichloride
• C. nitrosyl chloride
• D. nitrogen

Answer 1

Answer: (B)

nitrogen trichloride

In excess of ammonia, chlorine forms ammonium chloride.
$8N{H}_3\left(g\right)+3C{l}_2\left(g\right)\to 6N{H}_{4}Cl\left(s\right)+N_2\left(g\right)$
But in excess of chlorine, ammonia forms nitrogen trichloride.
$3C{l}_2+N{H}_3\to NC{l}_3+3HCl$
