Question

Which compound gives white precipitate with AgNO$_3$ in ethanol?

• A. CH$_3$CH$_2$Br
• B. C$_6$H$_5$CH$_2$Cl
• C. (CH$_3$)$_3$CCl
• D. CH$_3$Cl

Hint:

Compounds like alkyl halides that can form stable halide ions (like Cl$^-$) react with AgNO$_3$ to give a white precipitate of AgCl.

Answer 1

The Correct Option is B

C$_6$H$_5$CH$_2$Cl (benzyl chloride) will give a white precipitate of AgCl when treated with AgNO$_3$ in ethanol because the chloride ion can react with Ag$^+$ to form a precipitate.
