Study Notes
Elimination reaction of 2-bromopentane
- The elimination reaction of 2-bromopentane to form pent-2-ene is a β-elimination reaction.
- It follows the Zaitsev rule, which states that the more substituted alkene is the major product.
- The reaction is a dehydrohalogenation reaction, a type of elimination reaction where a hydrogen halide is removed from a molecule.
Stereoisomers of CH3CHOHCOOH
- Two possible stereoisomers of CH3CHOHCOOH, which are optically active, are called enantiomers.
- Enantiomers are stereoisomers that are non-superimposable mirror images of each other.
SN2 reaction on chiral centres
- In an SN2 reaction on chiral centres, there is inversion more than retention leading to partial racemization.
- This means that the product will be a mixture of both enantiomers, with the inverted product being the major product.
