wat? hydraquinone is giving or not giving?

actually catechol n resorcinol do not give d test n hydroquinone is giving test cud u explain

the answewr lies in the question u asked. if aromatic alcohols are oxidisable, then this will also be oxidisable. as u know it is a aromatic di-ol na.

is hydroquinone easily oxidisable

@akand, u only try, the clue i can give is that C2-C23 centre is very easily prone for oxidation

@manipal: i donno from where i read it, its been long i stopped organic. i think it was given by our sir.

alcohals,ketones---->tollen test
maine pehle kabhie bhi nahi suna
jahan tak mujhe pata hai it is given by aldehydes only

wel try for CH₃CH(OH)COCH₃.......WATS D PRODUCT??

dude, woh tho depends na........

i cant definitely say just alcohol will get oxidised to ketone, and actually it depends, but

watever information i gave, its right, i am damn sure

@mathie thanks for d information

but mathi.........then wat wud d product be????

aromatic alocohols, let me have a look

in your question, aplha hydroxy ketones gice it because

two adjacent carbons, one containing carbonyl and other contains alcohol. this is very easiiily prone to oxidation.

wel i dont think so........... i dunno about d second one but 1st one definitely no...

the following give tollen`s test, kindly remember if u can

1formic acid
2all formates
3alpha keto carboxilic acids
4alpha hydroxy carboxylic acids
5alpha hydroxy ketones

i read it sumwhr n was confused
