Question

Which of the following organic compounds unable to give precipitation after reaction with silver nitrate ( $AgNO_{3}$ )?

• A. $PhCH_{2}Cl$
• B. $\left(\right.\left(CH\right)_{3}\left(\left.\right)_{3}CCl$
• C. $CH_{3}CH=CH-Cl$
• D. $CH_{2}=CH-CH_{2}-Cl$

Answer 1

Answer: (C)

$CH_{3}CH=CH-Cl$ does not give ppt. with $AgNO_{3}$ as $\text{AgCl}$ will not be formed due to partial double bond character between $C-Cl$ due to resonance.
