The conversion of 2 − methyl − 2 − butene into 2 − methyl − 1 , 3 − butadiene and ethylbenzene into 3 − phenylacrylonitrile and the product of the Diels Alder reaction is to be determined. Concept introduction: ▸ The reagent NBS is used for the allylic bromination of the alkene and the mechanism of the reaction involves the formation of free radicals. ▸ The dehydrohalogenation of halo alkene takes place in the presence of a base like KOH to form the alkene as a product. ▸ The process in which the alkene is treated with ammonia and oxygen for the formation of nitrile is known as Ammoxidation. ▸ A reaction in which dienes and dienophiles react with each other to form the cyclic compound is known as Diels Alder reaction.

Complete the reaction in the drawing area below by adding the major products to the right-hand side. If there won't be any products, because nothing will happen under these reaction conditions, check the box under the drawing area instead. Note: if the products contain one or more pairs of enantiomers, don't worry about drawing each enantiomer with dash and wedge bonds. Just draw one molecule to represent each pair of enantiomers, using line bonds at the chiral center. More... No reaction. my ㄖˋ + 1. Na O Me Click and drag to start drawing a structure. 2. H +

Predict the major products of this organic reaction: 1. NaH (20°C) 2. CH3Br ? Some notes: • Draw only the major product, or products. You can draw them in any arrangement you like. • Be sure to use wedge and dash bonds where necessary, for example to distinguish between major products that are enantiomers. • If there are no products, just check the box under the drawing area.
