Draw the correct mechanism for the first step of the reaction sequence. Just show the reactants and curved arrows. Do NOT show the products. Include lone pairs and formal charges. Only draw out acidic hydrogen with a covalent bond from the heteroatom from which the hydrogen are attached. CH3CHSH + CH3O- Edit A Draw the correct mechanism for the second step of the reaction sequence. Just show the reactants and curved arrows. Do NOT show the products. Include lone pairs and formal charges. C (which has the partial structure A-CHCHO) + CH CH A (contains sulfur) + B Edit Draw the correct mechanism for the third step of the reaction sequence. Just show the reactants and curved arrows. Do NOT show the products. Include lone pairs and formal charges. When drawing water, draw out both hydrogen with covalent bonds from the oxygen atom. C + HO DE (which is inorganic)
