Draw the structure of the organic product of the following dehydration reaction. If more than one product is possible, draw the structure of the major product. OH CH3 H2S04 CHCCH CH3 heat CH

Many insects utilize cyclic ketal structures as pheromones such as the structure shown below. The biosynthetic pathway involves the cyclization of this acetal from the straight chain structure. Draw the straight chain structure that could be used to form this acetal. Use wedges and dashes to correctly depict the stereochemistry. H3C- >
