Haloalkanes and Haloarenes
A
$\text{HOH} / \text{OH}^{-}$
12%
B
Tollens reagent
19%
C
Both $\text{HOH} / \text{OH}^{-}$ and Tollens reagent
26%
D
$\text{HOH} / \text{OH}^{-}$ , Tollens reagent and ceric ammonium nitrate
44%
Solution:
This will give red colour with ceric ammonium nitrate
$\text{CH}_{3} - \text{CH}_{2} - \text{CHCl}_{2} \overset{\text{HOH} / \text{OH}^{-}}{ \rightarrow } \text{CH}_{3} - \text{CH}_{2} - \text{CHO}$
This will give silver mirror with Tollens reagent.
