Finding out E and Z Isomers | Stereochemistry | Organic Chemistry #NEET, #jeeadvanced

This video discusses how to find out E and Z isomers of alkene. Z/E is used to distinguish the configurational isomers. Z is equivalent to cis and E is equivalent to trans.

1. The higher the atomic number of the immediate substituent atom, the higher the priority. For example, H–   C–   N–   O–    Cl–. (priority increases left to right)

2. If two substituents have the same immediate substituent atom, move to the next atom (away from the double bond) until a difference is found.For example, CH3–    C2H5–    ClCH2–    BrCH2–    CH3O–.
