Hll Name: 1. Give the expected products of E2 elimination for each of following reactions with reaction mechanisms (show all attacks with arrows) :: NAOCH Br CH3OH Н NAOCH3 н CH2OH Br
Alkyl Halides and their Reactions: Nucleophilic Substitution and Elimination l. Predict the major organic product for each of the following. (1 major structure is all that needed in each case). (3 points each) Br CH3ONa CH3CH2ONa (for "d", show elimination product only, there will also be some substitution) NaOH e, optically active (for "e", show substitution product or products only. If both enantiomers form, draw both) Is the product solution for reaction "e" above racemic or optically active? (1 point...

resonably be formed from each of the following compounds under yhe
indicated reaction.
4. Write the structures for all the alkene products (regio and stereo isomers) that could reasonably be formed from each of the following compounds under the indicated reaction conditions. Where more than one alkene is produced, specify the one that is the major product. (5) a. 3-Methyl-3-pentanol (sulfuric acid, 80°C) b. 2,3-Dimethyl-2-butanol (phosphoric acid, 120°C)

need help with these practice problems please :) if can help with
all would greatly appreciate.
