Woodward-Fieser rule for calculating absorption maximum in conjugated dienes

Woodward-Fieser rule for calculating absorption maximum in conjugated dienes: This video explains about how to calculate absorption maximum i.e. lambda max in conjugated diene systems. This video clearly explain about different terminology e.g. acyclic dienes, homoannular dienes, heteroannular dienes, endocyclic and exocyclic double bonds. In this video, different examples (5) are discussed for the better understanding on how to use Woodward empirical rule to calculate lambda max. One example having cross-conjugation is also discussed for the proper marking and correct consideration. One example having both the cyclic dienes systems i.e. homoannular and heteroannular dienes is also discussed to clarify and the selection of the correct diene system and taking the correct base value for the calculation. After watching this video you will be able to mark the correct conjugated diene system properly and calculate the lambda max value correctly and very easily.
