Question

difference between benzophenone and acetophenone

Answer 1

Benzophenone and acetophenone both are aromatic ketones.
 *Benzophenone(C₆H₅COC₆H₅)
 *Acetophenone(C₆H₅COCH₃)

Acetophenone and Benzophenone can be distinguish by using iodoform test. However, Benzonphenone does not contain any free methyl group so it will give a negative test.

 1) C₆H₅COCH₃ + 3NaOl → C₆H₅COONa + CH₃ +2NaOH
 Acetophenone + Sodium Hypoiodite → Sodium Benzate + Iodoform(yellow ppt)

 2) C₆H₅COC₆H₅ + NaOl → No yellow ppt of CH₃
Benzophenol + Sodium Hypoiodite → No yellow ppt of CH₃

Answer 2

acetophenone 
the aromatic ketone phenyl methyl ketone, used in the manufacture of very many organic compounds 

benzophenone

Any of a class of aromatic ketones based on the parent compound diphenylketone (C6H5)2CO; used, amongst other things, as ingredients in sunblock.
