Q.
Methyl ketone is identified by:
Bihar CECEBihar CECE 2005Aldehydes Ketones and Carboxylic Acids
Solution:
(a) lodoform test is done to detect presence of $ C{{H}_{3}}CO $ group in organic compounds.
(b) Fehling solution identifies aldehydes
(c) Tollens reagent identifies aldehydes
(d) Schiffs reagent identifies aldehydes
Methyl ketone is $ C{{H}_{3}}-\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,-R. $
$ \because $ It has $ C{{H}_{3}}-\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\, $
group. It is tested by using iodoform test. The compound having $ C{{H}_{3}}CO $ group give yellow ppt. on reaction with $ {{I}_{2}} $ and aqueous alkali.
