Question

$S_1$: AgCl with liquid ammonia forms a complex $\left[Ag\right(N{H}_3{)}_2{]}^{+}$.
$S_2$: Ammonium dichromate on heating decomposes to give nitrogen and a green colored compound.
$S_3$: CaNCN on hydrolysis produces a white precipitate and a gas which turns filter paper moistened with copper sulphate solution deep blue.

• A. T T T
• B. T F T
• C. F F T
• D. T T F

Answer 1

The correct option is A T T T

$AgCl+N{H}_3\to \left[Ag\right(N{H}_3{)}_2{]}^{+}+C{l}^{-}$
$\left(N{H}_4\right)C{r}_2{O}_7\stackrel{\Delta }{\to }{N}_2+C{r}_2{O}_3+4H_{2}O$
$CaNCN+3H_{2}O\to \underset{(whiteppt.)}{CaC{O}_3}+2N{H}_3$
So, all the three statements are correct.
