1. Step by Step direction on how to identify the product of a substitution reaction and the type of mechanism involved in the reaction What is the major product of the following reaction? NaSH Dimethylsulfoxide (DMSO) Br: primary (1°) bromide Br Br DMSO NaSH Na SH SH SH 3-methylbutane-1-thiol Product of reaction is 3-methylbutane-1-thiol Steps to determining the product of a substitution reaction 1. Identify the type of alkyl halide involved in the reaction: Recall that primary halides tend to go through a SN2 mechanism 2. DMSO is the solvent and favors a SN2 mechanism 3. Na SH, sodium hydrosulfide in a salt with the nucleophile Hydrosulfide (HS and Nation) 4. The Hydrosulfide (HS) will attack the carbon attached to the bromine to form a substitution product. 5. This is an SN2 reaction, and it will produce the organic thiol compound.

by Step direction on how to identify the product of an elimination reaction and the type of mechanism involved in the reaction What is the major product of the following dehydration reaction? H₂SO4 HỎ 1 3 4 H H₂H HO 2 H H H co HO√/2 НО. HHE 3° carbocation 3° carbocation oxonium + H-SO₂H 80°C H H.O: H Q-H HO H₂SO4 80°C 3 tertiary (30) alcohol 80°C slow RDS H H oxonium H removal of B-HHH ·L 3° carbocation removal of B-H H. ? H Major: More substituted alkene H 20 H H 2-methylbut-1-ene Minor H Minor Product: Less substituted alkene 2-methylbut-2-ene Major Steps to determining the major product of an elimination reaction 1. Identify the type of alcohol involved in the reaction: This is a tertiary alcohol and go through a SNI mechanism 2. H₂SO4 is a non- nucleophilic acid, and it will protonate the alcohol to make it a better leaving group. 3. Oxonium ion formed will dissociate to form a tertiary carbocation and water. 4. The ß-carbon with the lesser amount of H will be removed to give the more thermodynamically stable alkene (trisubstituted alkene.(Zaitsev's rule) 5. The ß-carbon with the higher amount of H will be removed to give the less thermodynamically stable alkene (disubstituted 6. The major product is the trisubstituted alkene, 2-methylbut-2- ene.

Explain the mechanism of the following reaction and identify the major product of the reaction that you are assigned OH H₂SO4 80°C

In this discussion board, you will post your illustration on how to determine the mechanism (E1, E2, SN1, or SN2) of the reaction that you are assigned. You will also explain how to find the major product of the reaction as well.. P
