The structures of two different tetra methyl derivatives of cyclooctatetraene with methyl groups on four adjacent carbon atoms are to be drawn. Concept introduction: Cyclooctatetraene is nonplanar with four short and four long carbon-carbon bond distances. Cyclooctatetraene is a tub-shaped eight-membered ring having a single Lewis structure having alternating single and double bonds. Because of its nonplanar structure, there is no possibility of the π electron delocalization needed for aromaticity.
