Question

Give simple chemical tests to distinguish between the following pairs of compounds: Acetophenone and Benzophenone

Answer 1

HELLO DEAR,




These can be distinguished by the iodoform test.

$\bold{iodoform\; test.}$ acetophenone being a methyl ketone when treated with NaOI (${I_2/NaOH}$) gives yellow PPT. of Iodoform but benzophenone does not.

$\bold{C_6H_5COCH_3 + 3NaOI \to C_6H_5COONa + CHI_3\downarrow + 2NaOH}$



$\bold{C_6H_5COC_6H5 + NaOI \longrightarrow No\; yellow\; ppt. \;of \;CH_3}$



I HOPE IT'S HELP YOU DEAR,
THANKS

Answer 2

HEY DEAR ... ✌️

___________________________

Here's , Your Answer :-

=) First understand :-

_____________________________

(i) Acetophenone = C6H5COCH3 .

----------------------------------------------------

(ii) Benzophenone = C6H5COC6H5 .

=================================

⏺️ We can distinguish them by using Iodoform Test .

So , Reactions :-

1.) For Acetophenone .

=] C6H5COCH3 + 3 NaOI ➡️ C6H5COONa + CHI3 + NaOH .
Yellow ppt will be seen .


2.) For Benzophenone .

=] C6H5COC6H5 + NaOI ➡️ No yellow ppt will be seen .
