is the admit card the confirmation thing u get saying that all details are filled ?

could u please explain this reaction ?

wat about now ?

plz rate if found useful :)

At least one of the reagents must be enolizable (have an ?-proton and be able to undergo deprotonation to form the enolate anion). for more info - http://en.wikipedia.org/wiki/Claisen_condensation

wat exactly is the function of Na+NH3 when added to unsat. compds ?

na, thats the point ! OP Agarwal says oxidising power decreases from ClO- to ClO4- ... which cant be true !

always check the stability of conj base ! ClO4- is more stable coz the Cl-O bond has a greater multiplicity

@nitigya- "we all know dat 30 radical is stable hence the intermediate corresponding to answer (a)
is deeveloped , now d three degree radical is abstracts H and we get answer (a)"

could u pls explain this agen ! be a li'l clearer ..

1) is "thermal stability" the same as just "stability" ? if yes , then since "more acidic" means "less stable" , thermal stability of HClO4 should be low compared to HClO , but this is not the case.

2) how do u decide oxidising power ? eg- oxidising power of ClO- is more than ClO4- , but this seems illogical as ClO4- has so many "O"s to give away !

3) why is HI a stronger acid than HCl but oxyacids of Iodine weaker than the corresponding Chloro-oxyacids ?

all info courtesy OP Agarwal - JPNP. any answer with a semblance of correctness will be rated :) :) :) ty !

regardless of whether ur adding hyd halides or watever ... as long as ur taking a free radical , stabilisation is most imp, right ? pls explain

so how do u explain this ? its by free rad mechanism too... the whole point is that tha radical has gotta be stabilised !

@chilbi- but "b)" is anti markownikoffs too right ? pls take a look at it agen and explain ...
@kavindra - thats for simple halogenation, not for addition on a double bond, right ?

how true, madmax ! this was a lovely collection...

gee thanks , guys :) but how can u predict whether sumthings gonna invert or retain by just lookin at the reagents theyv used ?
