Question

Which of the following statement(s) is/are correct regarding reaction of ammonia with chlorine?

• A. When excess ammonia is used, a yellow oily liquid is formed
• B. When excess ammonia is used, a gas is evolved
• C. When excess chlorine is used, a gas is evolved
• D. When excess chlorine is used, $NC{l}_3$ is formed

Answer 1

Answer: (B), (D)

When excess chlorine is used, $NC{l}_3$ is formed

When ammonia is in excess,
$8N{H}_3\left(g\right)+3C{l}_2\left(g\right)\to N_2\left(g\right)\uparrow +6N{H}_{4}Cl\left(aq\right)$

When chlorine is in excess,
$N{H}_3\left(g\right)+3C{l}_2\left(g\right)\to \underset{\text{yellow oily liquid}}{NC{l}_3\left(l\right)}+3HCl\left(aq\right)$
Options (b) and (d) are correct.
