Question

$C{H}_{3}C{H}_{2}C{H}_{2}C{H}_3\stackrel{B{r}_2/hv}{\to }$
Major product in the above reaction is:

• A. racemic mixture
• B. meso
• C. diastereomers
• D. constitutional isomers

Answer 1

Answer: (A)

racemic mixture

$Br$

$C{H}_{3}C{H}_{2}C{H}_{2}C{H}_3\stackrel{B{r}_2/h\nu }{\to }C{H}_{3}C{H}_{2}C{H}_{2}Br+C{H}_3\stackrel{|}{CH}C{H}_{2}C{H}_3$

Thus, a racemic mixture is obtained. A racemic mixture is one that has equal amount of left and right handed enantiomers of a chiral molecule.
