No worries! Glad I could help.

I'm afraid I can't answer your other question - I'm doing a different board (OCR). Sorry

No flame tests or oxidation in unit 1.

Hey guyz,
 doubt in organic chemistry P1

Q1) which compound is unaffected by hot alkaline potassium manganate (VII) and gives hydrogen when treated with sodium?
a.(CH3)2CHCOCH3
b.(CH3)3COH
c.CH3CH2CH(OH)CH3
d.CH3CO2CH(CH3)2

I thought da answer was C but it is wrong  :'( dunno why!!!!!

I really appreciate any help from u guyz  :-*

nid404:
See b is a primary alcohol which can get oxidised, c is a secondary alcohol which can also get oxidised
so it leaves us with a and d
a is a ketone, which won't be affected by KMNO4...it won't get oxidised further
so it leaves us with d....
By the way what does the ms say?...cuz i keep forgetting reaction mechanisms...so i may have messed up
