Question

Which of the following halogen exchange reaction will occur in acetone?

• A. $R =1+ NaCl \longrightarrow$
• B. $R = F + KCl \longrightarrow$
• C. $R = Cl + Nal \longrightarrow$
• D. $R - F + AgBr \longrightarrow$

Answer 1

Answer: (C)

$R - Cl + Nal \rightarrow R - I + NaCl$
This reaction will occur in acetone because of two reasons:
(i) The reactant $Nal$ is more soluble in acetone.
(ii) Secondly, the formed product $NaCl$ will precipitate out
