JEE Main Chemistry question
CH_3-\underset{\displaystyle OH}{\underset{|}{CH}}-CH_2-CH_3 \xrightarrow[-H_2O]{H^+} [F] \xrightarrow{Br_2/CCl_4} C_4H_8Br_2 (5 such products are possible)
How many structures of are possible?
Answer: (D)
Solution
Acid-catalysed dehydration of butan-2-ol can proceed by loss of a proton from either adjacent carbon, giving three distinct alkenes: but-1-ene, cis-but-2-ene and trans-but-2-ene (the two but-2-enes are distinct geometrical isomers of the same constitution). Each of these three alkenes, on addition of ,
