What are enantiomers? Write about their properties with examples.

(N/A) Enantiomers: Stereoisomers that are non-superimposable mirror images of each other are called enantiomers. They are chiral.
$(b)$ Examples:
$(i)$ Butan-$2$-ol $(CH_3CH(OH)CH_2CH_3)$
$(ii)$ $2$-Chlorobutane $(CH_3CHClCH_2CH_3)$
$(iii)$ $2,3$-Dihydroxypropanal $(OHC-CH(OH)-CH_2OH)$
$(iv)$ Bromochloroiodomethane $(BrClCHI)$
$(v)$ $2$-Bromopropanoic acid $(CH_3CHBrCOOH)$
$(c)$ Properties of enantiomers:
$(i)$ Physical properties such as melting point,boiling point,solubility,and refractive index are identical.
$(ii)$ Their chemical properties are also identical.
$(iii)$ Enantiomers differ only in their interaction with plane-polarized light.
$\Rightarrow$ If one enantiomer is dextrorotatory $(d)$ or $(+)$,the other is levorotatory $(l)$ or $(-)$.
$\Rightarrow$ These two isomers rotate the plane of plane-polarized light by the same magnitude but in opposite directions. Therefore,an equimolar mixture of two enantiomers has zero optical rotation and is called a 'racemic mixture'. $A$ racemic mixture is represented by the prefix $dl$ or $(\pm)$.
