Predict the products the alkenes shown below would produce on exposure to each of the reagents (i)-(iv) (4 reactions X 5 alkenes = 20 products). Pay attention to both regiochemistry and stereochemistry (syn or anti addition). You may draw just one enantiomer of any chiral product, though both enantiomers will be produced in equal amounts.
