meso-2,4-Dichloropentane : (Fischer Projection Formula)

meso-2,4-Dichloropentane has a plane of symmetry (σ) passing through the middle CH 2 group (dashed line): the upper half (C 2 with H, Cl, CH 3 ) is the mirror image of the lower half (C 4 ). The molecule is achiral (meso) although it has two stereocentres.
