Name a compound having two dissimilar asymmetric carbon atoms and write its struture. What type of isomulas does it exhibit? Draw Fischer projection formulas of the isomers and comment on their optical activity. How are the isomers related to each other?

Explanation

Compound containing two dissimilar asymmetric carbon atoms is 3 - bromobutan - 2 - ol `(CH_(3)CHOHCHBrCH_(3))`. Compound may have `2^(n)` ( n = no. of dissimilar asymmetric carbon atom) = `2^(2) = 4` possible stereoisomers. Fischer projection formulas of these isomers are as follow :

All the isomers are optically active
The relations among the isomers are as follow: (I,II) and (III,IV) are two pair of enantiomers whereas (I,III), (I,IV), (II,III) and (II,IV) are four pairs of diastereomer.
