Stereochemistry-----
In the presence of β −hydrogen atom, an elimination reaction is seen in Haloalkane. However, if there are more than 1 β−hydrogen atoms present, more alkenes will be generated from multiple eliminations happening at the same time.
Stereochemistry can be of various types:
Regioselectivity – It includes the selective production of a major product as a regioisomer. The regioisomers are alkenes exhibiting double bonds.
Stereoselectivity – The product isomer is formed due to the reaction happening on a choice pathway even when numerous reaction pathways are present.
Stereospecificity – A reactant's stereochemistry determines the product's stereochemistry.
Chemoselectivity – Reaction takes place on one functional group within a molecule.
