$F e C l_{3}$ reacts with ammonium hydroxide to give a reddish brown precipitate of metallic hydroxide which is insoluble in excess of $N H_{4} O H$ . Name this precipitate.

Q. The correct statement(s) about the following reaction sequence is/are:

C u m e n e (C_{9} H_{12}) i) O_{2} - ----- \to i i) H_{3} O^{+} P C H C l_{3} / N a O H - -------- \to Q (m a j o r) + R (m i n o r)

Q N a O H - ----- \to P h C H_{2} B r S

Q. (A) (yellow coloured solution) changes to light green coloured solution (B) on passing

H_{2} S

gas. (A) and (B) both give white precipitate with

B a {C l}_{2}

solution, insoluble in conc.

H C l

. A gives blue coloured ppt (C) with

K_{4} [{F e (C N)}_{6}]

, (B) does not. Here,
(A) :

{F e C l}_{3}

(B) :

{F e C l}_{2}

F e_{4} [F e (C N_{6})]_{3}

If true enter 1, else enter 0.
