Organic chemistry
Sorry to sound dumb but do haloalkenes exist?
Y is heated with aqueous sodium hydroxide. Dilute nitric acid and aqueous silver nitrate are added to the solution. A yellow precipitate forms. Y also contains 3 carbon atoms. A few drops of Y are added to bromine solution, the yellow solution becomes colourless.
Would Y be iodoprop-1-ene?
CH2=CHCH2(I)

anyone?
yeah, the OH- is nucleuphile and subsitutes out the Iodide ion (which doesnt take a lot, considering the weakness of the bond). So
Iodide ions form yellow ppt with the AgNO3
and the double bond reacts with the bromine water decolourising it. To be sure though, add conc NH3, if the ppt doesnt dissolve you're sure its iodo... (sometimes ppt colours are misleading due to impurities)

so CH2=CH=CH2(I) + Br2 = 
visesh
CH2=CH-CH2(I) + Br2 -----> CH2Br-CHBr-CH2(I)
yeah, bromine breaks the double bond and takes its place with 2 Br atoms.

chloroform is not a figment of your imagination.
chloroform is not a haloalkene - CHCl3
however vinyl chloride (the monomer from which PVC is made) is a haloalkene - CH2=CHCl
chloroethene for the purists
