The geometry of a molecule

The geometry or shape of a molecule has a signifcant effect on the physical properties of the molecule. The chirality of carbon can determine its optical activity. Even if two compounds are of the same formula, one compound could be transparent the other opaque just because of a slight difference in geometry. The cis and trans configurations of fatty acids affect the melting point even if the fatty acids have similar formulas. The trans-fatty acids have a relatively high melting point and are likely to acculmulate and clog arteries as...
