Chiral molecules are molecules that CANNOT be superimposed on their mirror image.

#H_2CBrF# is achiral.

#H_2C=CHCF_3# is achiral.

#Br_3C-C^("*")H(Cl)Br# has a chiral centre (starred), and could support a pair of optical isomers.

#H_3C-CH_2F# is achiral.

#H_3CF# is achiral.

#H_3C-""^("*")C(H)(Br)CH_2CH_3# is chiral.

#""^+PBrCl_2(CH_3)# is achiral.
