(a) Interpretation: The diastereomers of oct − 4 − ene that yields a mixture of two enantiomers on reaction with Br 2 is to be stated. Concept introduction: The addition of Halogens to alkenes is a stereospecific reaction. The resultant product is meso compound, if alkene is cis and addition of halogen is syn addition. If addition of halogen is anti, then the resultant products are racemic mixture. In case of trans alkene, the resultant product is meso, if addition of halogen is anti. The resultant products are racemic mixture, if the addition of halogen is syn.

Interpretation Introduction
(a)
Interpretation: The diastereomers of oct−4−ene that yields a mixture of two enantiomers on reaction with Br2 is to be stated.
Concept introduction: The addition of Halogens to alkenes is a stereospecific reaction. The resultant product is meso compound, if alkene is cis and addition of halogen is syn addition. If addition of halogen is anti, then the resultant products are racemic mixture. In case of trans alkene, the resultant product is meso, if addition of halogen is anti. The resultant products are racemic mixture, if the addition of halogen is syn.
Interpretation Introduction
(b)
Interpretation: The diastereomers of oct−4−ene that yields a single meso compound, (4R,5S)−4,5−dibromooctane is to be stated.
Concept introduction: The addition of Halogens to alkenes is a stereospecific reaction. The resultant product is meso compound, if alkene is cis and addition of halogen is syn addition. If addition of halogen is anti, then the resultant products are racemic mixture. In case of trans alkene, the resultant product is meso, if addition of halogen is anti. The resultant products are racemic mixture, if the addition of halogen is syn.
