Optically active molecules

WebMar 8, 2016 · The compound has two chiral carbons, so it will be optically active. 1,2-Dichloro-2-methylpentane The structure of 1,2-dichloro-2-methylpentane is Here, C2 is a chiral carbon. The 4 groups attached to C2 are CH3, Cl, CH2Cl, and CH2CH2CH3. The compound has a chiral carbon, so it will be optically active. Answer link WebPHY 192 Optical Activity 3 Fig. 4: Light intensities and polarization with rotation of E vector by medium. Optically active organic molecules have a spiral structure like a right-handed or left-handed screw. It is this spiral nature of the molecule, which rotates the plane of polarization of light passing through it.
