Identify the set of reagent/reaction conditions 'X' and 'Y' in the following set of transformation: CH_(3)-CH_(2)-CH_(2)Br overset("X")to"Product"overset(Y)to CH_(3)-underset(Br)underset(|)(C)H-CH_(3)X=dil. Aqueous NaOH, 20^(@)C, Y=HBr/acetic acid, 20^(@)C.

Answer»

X=dil. Aquous NaOH, `20^(@)C,Y=Br_(2)//CHCl_(3),0^(@)C`41
X=conc. Alcoholic NaoH, `80^(@)C`, Y=HBr/acetic ACID, `20^(@)C`
X = dil. Aqueous acid, NaOH, `20^(@)C`, `Y = Br_(2)//CHCl_(3), 0^(@)C`
X = conc. Alcoholic NaOH, `80^(@)C`
`Y = Br_(2)//CHCl_(3), 0^(@)C`

Solution :Conc. Alc. NaOH at `80^(@)`C brings about dehydrohalogenation while HBr/acetic acid at `20^(@)C` brings about Markovnikov's ADDITION.
