(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.
(EXM 2, PRBLM 3) Here is this problem, can you explain it to me and show how its done. Thank you I need to see the work for like prbl solving.
can someone draw out the reaction mechanism for this reaction showing all bonds, intermediates and side products

What would be the best choices for the missing reagents 1 and 3 in this synthesis?
1. PPh3
3
2. n-BuLi
• Draw the missing reagents in the drawing area below. You can draw them in any arrangement you like.
• Do not draw the missing reagent 2. If you draw 1 correctly, we'll know what it is.
• Note: if one of your reagents needs to contain a halogen, use bromine.
