Question

Please give the principal organic product of each reaction (unless being asked otherwise) please specify stereochemistry if it applies. 

The image contains several chemical reactions involving different compounds and solvents, depicted schematically with arrows indicating the transformation direction.

1. **First Reaction:**
   - Reactants: A chlorinated compound (Cl) and sodium methoxide (ONa).
   - Solvent: DMSO.
   - Product: Substitution product only.

2. **Second Reaction:**
   - Reactants: An iodinated compound and sodium methoxide (NaOCH₃).
   - Solvent: Methanol.
   - Transformation indicated with an arrow; no specific product depicted.

3. **Third Reaction:**
   - Reactants: A brominated branched alkane and hydrogen sulfide ion (HS⁻), with 1 molar equivalent.
   - Solvent: DMSO.
   - Product: Substitution product only.

4. **Fourth Reaction:**
   - Reactants: A dibromoalkane and hydrogen sulfide ion (HS⁻), with 1 molar equivalent.
   - Solvent: DMSO.
   - Product: Substitution product only.

5. **Fifth Reaction:**
   - Reactants: An alkyl tosylate (TsO) and sodium methoxide in ethanol.
   - Conditions: Heat.
   - TsO is defined as a para-toluenesulfonyl group depicted structurally.

6. **Sixth Reaction:**
   - Reactants: A dibromo compound and a cyclic structure with an alcohol (OH) group.
   - Reagent: (1 molar equivalent) of a cyclic compound containing an oxygen atom.

Each reaction involves a substitution process where parts of the molecules are replaced by other functional groups, emphasizing the use of different solvents and conditions to control the reaction outcome.
