2. The reactions performed during this week's lab proceed via tertiary carbocation intermediates. These carbocations can react with nucleophiles/bases (ie. Cl and Br) to produce both Syl and El products. For each of the structures below, provide all of the possible substitution and elimination products: 1.) HSO,, H20 2.) NH Br OH

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.

wides such as A are formed by combining peracids with alkenes. This reaction is similar to the of bromonium ion b from an kene. When epoxides are reacted with acid, an intermediate sformed that is structurally similar to b. Likewise, when water is added to Bit forms a product in a mechanism identical to the one from bibe. Draw the structures of A, B and C CPA HO HO C 4. Using the information abone draw the products of the...
