![]() ![]() the enantiomer of this compound will rotate light by the same amount, but the opposite direction. if plane-polarizing light passes through a solution of an optically active compound, the molecule rotates the orientation of the polarized light by an angle of alpha. a polarizing filter allows light waves oscillating only in a particular direction to pass, producing plane-polarizing light. ordinary light is unpolarized and has waves vibrating in all possible planes perpendicular to its direction of motion. compound is optically active if it has the ability to rotate plane-polarized light. ![]() Pairs of enantiomers have identical chemical and physical properties with one exception, optical activity. if the two highest priority are on opposites, it's E (German entegegen, meaning opposite). if two higher priority substituents are on the same side, it's Z (German Zusammen means together). higher atomic weight atoms will take priority over double bonds. if two atoms are the same, a double bond takes priority over a single bond. if two atoms are the same, look at the next atom attached to each the group that has the second atom with higher molecular weight has higher priority.ģ. the group with the highest atomic weight atom has the highest priority.Ģ. from C of interest, determine the atomic weight of the first atom encountered along each bond. for compounds with more than one substituent on either C of the double bond, there's the EZ system where the highest priority substituent has to be determined.ġ. if the substituents on the carbons are both above the double bond, it's cis. because a double bond can't rotate, the substituents are fixed relative to each other and the bond. Compounds that differ in the position of substituents attached to the two carbons that form a double bond. ![]()
