Question
The reagents which can be used to distinguish acetophenone from benzophenone is (are)
A.
2, 4 - dinitrophenyl hydrazine
B.
aqueous solution of $$NaHS{O_3}$$
C.
Benedict reagent
D.
$${I_2}$$ and $$N{a_2}C{O_3}$$
Answer :
$${I_2}$$ and $$N{a_2}C{O_3}$$
Solution :
The structures of acetophenone and benzophenone are
When acetophenone containing
unit, is treated with $${I_2}$$ and $$N{a_2}C{O_3}$$ it forms yellow precipitate of $$CH{I_3}$$ whereas benzophenone does not give this test.Acetophenons gives iodoform test due to presence of $$ - COC{H_3}$$ group.
