a}first use HBr and then use aqueous naoh/koh b}same as a part c}use alcoholic koh
hemant December 7, 2010 at 11:38 am
a> H2O and H2SO4 b> H2O and H2SO4

a)Hydro-boration oxidation method. b)Hydro-boration oxidation method. c)Simple addition of H2O.
vaibhav kumar gautam December 7, 2010 at 1:17 pm
in 1st add hbr inpresence of h2o2 and then add oh- in 2nd and 3rd add h3o+ major product will be 3rd and minor is 2nd
Havan December 7, 2010 at 1:52 pm
a)Treat with HBr in presence of peroxide, and then treat with Aq. KOH/NaOH.
b)Same as (a)
c) Treat with HBr, then treat with aq. KOH/NaOH.
I think this is correct to my knowledge. If any mistake, please let me know. 🙂

I DEHYDROBORATION 3 HBR AND THEN ALC KOH…
priyanshu lilha December 7, 2010 at 3:01 pm
1.hydroboration oxidation 2.hydrroboration oxidation 3.acid catalysed hydration or oxymercuration demercuration

a) h2so4/hgso4 b)hydro boration oxidation c)h2o by markownikov
parth December 7, 2010 at 3:56 pm
one can be sythesized through hydrobaration oxidation… second can be synthesyzed through oxymercuration nd demercuration…. third can be synthesized with h2o in the presence of H+ ions……….
srinivas December 7, 2010 at 4:57 pm
1. chlorinate in the prescence of h2o2 ond then hydrolyse it with h2o.
2.chlorinate in the prescence of h2o2 ond then hydrolyse it with h2o.
3.just hydrolyse it.

Pathetic question this shows ypur incompetence in chemistry.. if u ve te time to ask sch qs then what the hell do u think u r doing dreaming abt IIT ? Get real…..
Himanshu December 7, 2010 at 8:13 pm
probably..for d first case ozonolysis.nnd then reduction.. for d second one..diborane method… for d third one..using acid hydrolysis ma help..

ans : b
Jenil December 7, 2010 at 9:44 pm
a) BH3 in presence of THF (tetra hydro furan) and then add H2O2…
b) BH3 in presence of THF (tetra hydro furan) and then add H2O2…
c) Aq KOH or mercuric acetate…(oxy mercuration) n den demercurate it by supplying heat…
Rohan December 7, 2010 at 10:32 pm
do catalytic hydrogenation and then do cholrination using thionl chlorid in presence of peroxide for first one,similarly for second one nt sure.. and with no peroxide for 3rd one…
shanu December 15, 2010 at 8:53 am
i think all these can be done with HydroBorationOxidation reaction.
Eshwar May 20, 2011 at 3:17 pm
a)Addition of Hydrogen Iodide followed by aq.KOH or NaOH. b)Oxy-Mercuration Demercuration(major product) c)Oxy-Mercuration Demercuration(minor product)
Siddharth Yadav May 30, 2011 at 11:26 am
a)Hydroboration Oxidation. b)Hydroboration oxidation. c)Oxymercuration Demercuration OR Simple Hydrolysis.

a&b are addition of water using antimarko i.e either use hydroboration+water for c it is marko addition so use oxymercuration/demercuration
neha July 14, 2011 at 11:39 am
a,b,c all of dem can be synthesized by treatng with HBr. a) shoulb be treatd along with peroxide.
pooja kapoor August 3, 2011 at 12:41 pm
a.1st using hbr and then using aq.koh or naoh………. b.hydroboronation oxidation…… c.oxy-mercuration-demercuration
Harsh Shivhare August 10, 2011 at 12:42 pm
we can simply use hydroboration oxidation method in a and b part,through which OH will stick acc. to the anti-markowmikoWs rule…….and H & OH sticks in syn-manner …….in c part we can use oxymercuration demercuration………
