Step-by-Step Solution
Verified Answer
The manner for the thermal and photochemical cyclizations of (2E,4Z,6Z,8Z)-2,4,6,8-decatetraene can be stated.
1Cyclization of tetraene
The reaction which involves tetraene’s cyclization. The electron pair number involved is even and its under thermal conditions through the ring of conrotatory closure for the yield of cyclic triene with two methyl group in cis relationship.
2Reaction will takes place in disrotatory ring
The reaction will takes place in disrotatory ring which yield the cyclic triene with two methyl groups in trans relationship.
