Ethyl bromide is warmed with aqueous NaOH, the solution is acidified with dilute $HNO X_{3}$ and $AgNO X_{3}$ solution is added. The observation is

Aa black precipitate of $Ag X_{2} S$
Ba white curdy precipitate of AgCl
Ca pale yellow precipitate of AgBr
Dno precipitate

Answer: C

Hydrolysis by aqueous NaOH gives ethanol and

NaBr

. After neutralising the excess alkali with

HNO X_{3}

, bromide ions give pale yellow

AgBr

with silver nitrate. Chloride would give white

AgCl

, and no sulphide is present.
