Butan-2-ol cannot be directly converted to 1,2-dibromobutane. The conversion can be carried out in two stages by first converting butan-2-ol into X, which is then reacted with bromine.(continued in answers)
butan-2-ol --?→ X --Br2→ 1,2-dibromobutane(a) State the name and draw the structural formula of X(b) State an equation and the conditions needed for the conversion of butan-2-ol into X.(c) Describe the mechanism of the second stage of the conversion, which occurs when bromine is added to X, using curly arrows to show the movement of electron pairs.--------------------------------------------Answer------------------------------------------a) but-1-ene, CH3–CH2–CH=CH2b)C2H5–CH(OH)–CH3 → C2H5–CH=CH2 + H2OHeat is needed and the it needs to be done in an acidic environment using concentrated sulfuric acid.c) Drawing will demonstrated during the session I cannot figure out if I can draw in here.
