In the cyclo addition reaction below, what caused the purple color of 2,3,4,5- Tetraphenylcyclopenta-2,4-dienone converts to white color in the formed 3,4,5,6- Tetraphenyldimethylphthalate? -00 gas 0 + the removal of carbon monoxide gas destructed the complex structure of 2,3,4,5-Tetraphenylcyclopenta-2,4. dienone Obecause the extended conjugation of the tetra phenyl groups in 2,3,4,5-Tetraphenylcyclopenta-2,4-dienone does not exist in case of 3,4,5,6-Tetraphenyldimethylphthalate. o the removal of carbon monoxide gas destructed the complex structure of 3,4,5,6 Tetraphenyldimethylphthalate, O because the extended conjugation of the tetra phenyl groups is increased in case of 3,4,5,6- Tetraphenyldimethylphthalate. the formation of the benzene ring caused the structure of 3,4,5,6-Tetraphenyldimethylphthalate to coplanar and resulted in more resonance forms
