1it depends on the stability of the geminal diol formed.
i.e. on R .

1well , if the compound is chloral , then it exists as a hydrate in aqeuous mdm.
or if hydrate is stabilized by H-bonding , then hydrate % is more.
1I don't think so sky , if there is no stabilizing factor this is not possible , but the attack is possible if acidic mdm is maintained , H2O can't simply go and attack . you need an electrophile. first protonate the sp2 hybrid C and then the ttack might be possible .
probaly gagar might be able to give us a better picture.
1hmm.. yup u are right...
i got your point...
then,,, .... !!#$$^%$&%!!!!!!!!
1According to Sky's answer you get back the reactant... two -OH bonds cannot be present on one Carbon.. Water molecule is lost...
So this is a reversible Reaction.. Stability of gem diols depend on presence of -I group,Steric Hindrance, intramolecular hydrogen bonding..
1that''s only generally.
in organic chemistry u always ahve a lot of exceptions . ;)
11When all do we have exceptions srinath? Pls reply. I'm floundering in organic chem and am desperate for some last minute info. [2]
1I've already given it . chloral is one example.
just write a molecule which will have intermolecular H-bonding on hydration.
one more.
chek out ninhydrin .also IUPAC is indane-1,2,3-trione.
.
try drawing it's hydrate. and give reason for stability.
