Predict the organic products, in any order, when the alkene shown is treated with hot, basic KMnO 4 followed by neutralization.

When treated with NaOH, the bromide below gives an alkene by the E2 mechanism, by elimination of the H atom indicated by the arrow: (a) Draw the Newman projection from which elimination takes place. (b) Draw the mechanism. (c) Draw the product with the proper stereochemistry. (d) Assign the proper stereochemical descriptor to the product. (e) Give the rate equation

Draw the structures of the initially formed enol tautomers in the reactions of propyne and dicyclohexylethyne with dicyclohexylborane followed by NaOHNaOH and H2O2H2O2

Predicts the major products for the following reaction.

Complete the following reactions, clearly indicating regio-and stereochemistry where applicable. In cases, where ortho-and para-products are formed, draw both.

Draw the structure of an alkene with one double bond that would give the following compound as the only product after ozonolysis followed by H2O2.

Draw all of the substitution and elimination products formed from thegiven alkyl halide with each reagent: (a) CH3OH; (b) KOH. Indicate thestereochemistry around the stereogenic centers present in the products,as well as the mechanism by which each product is formed.
