Question

Which of following does not give white precipitate of $AgCl$ on heating with silver nitrate.

• A. $C{H}_{3}C{H}_{2}Cl$
• B. $(C{H}_3{)}_{2}C{H}_{2}Cl$
• C. $(C{H}_3{)}_{3}CCl$
• D. $CC{l}_4$

Answer 1

The correct option is D $CC{l}_4$

$CC{l}_4$ does not give a white precipitate of $AgCl$ when it is treated with a solution of silver nitrate. It is because $CC{l}_4$ is a covalent compound and hence does not ionize by heating to give $C{l}^{-}$ ions, which is an essential requirement for the precipitation of $A{g}^{+}$ ions from $AgN{O}_3$.
