I mean why cant it be C
sorry.
Man put up the question...there will b less confusion!! heres the question:
16 Compound X on refluxing with aqueous sodium hydroxide gave mixture Y which on distillation
with acidified potassium dichromate(VI) produced propanone. Mixing Y with dilute nitric acid and
aqueous silver nitrate gave a cream precipitate.
What could compound X be?
A CH3CHBrCH3
B CH3CHICH3
C CH3CH2CH2Br
D CH3CH2CH2I
Ok so ur right that is could C...since it has Br...which is the only 1 that gives cream ppt
But if u react choice C with NaOH u get a primary alcohol, right???
Then if u react that primary alcohol with dichromate u get a aldehyde & finally carboxylic acid.
But the question says that u get ketone(propanone)...which is the oxidation a secondary alcohol
So if u react choice A with NaOH u get Secondary alcohol as Br replaces OH on that 2nd C atom
Then that secondary alcohol gives ketone on oxidation....
I hope this proves its A....
