Question

Which one of the following does not give white precipitate with acidified silver nitrate solution? (A)  (B) CH2 = CH—Cl (C) CH2 = CH—CH2—Cl (D) Both (a) and (b)

In (c), chlorine is attached to sp3 hybridized C-atom and C—Cl bond is more polar thus, it easily gives AgCl precipitate. In case of (a) and (b), chlorine is attached to sp2 hybridized C-atom and there is double bond character between C—Cl bond due to resonance i.e., C—Cl bond is stronger bond and hence chlorine cannot be easily replaced.

Q. Which one of the following does not give white precipitate with acidified silver nitrate solution?

$C H_{2} = C H — Cl$

$C H_{2} = C H — C H_{2} — Cl$

Both (a) and (b)

Q. Which one of the following does not give white precipitate with acidified silver nitrate solution?

CH2​=CH—Cl

CH2​=CH—CH2​—Cl

Both (a) and (b)

$C H_{2} = C H — Cl$

$C H_{2} = C H — C H_{2} — Cl$
