(a)

Interpretation Introduction

To determine: The complete Lewis structure for sodium triacetoxyborohydride.

Interpretation: The complete Lewis structure for sodium triacetoxyborohydride is to be drawn.

Concept introduction: The Lewis structure shows the connectivity between atoms by identifying the lone pairs of electrons in a compound. Lewis structures are also called Lewis dot structures. The valence electrons around an atom are shown by dots. Bonds between atoms are shown by lines and the lone pair of electrons is shown by a pair of dots.

(b)

Interpretation Introduction

To determine: The mechanism for the reduction of an aldehyde by sodium triacetoxyborohydride.

Interpretation: The mechanism for the reduction of an aldehyde by sodium triacetoxyborohydride is to be proposed.

Concept introduction: Sodium triacetoxyborohydride is a mild reducing agent that reduces aldehydes much more quickly than ketones. It is used to reduce the aldehydes in the presence of ketones.

gas, Cl¬CH2CH2¬S¬CH2CH2¬Cl, was used as a poisonous chemical agentin World War I. Mustard gas is much more toxic than a typical primary alkyl chloride. Itstoxicity stems from its ability to alkylate amino groups on important metabolic enzymes,rendering the enzymes inactive.(a) Propose a mechanism to explain why mustard gas is an exceptionally potent alkylatingagent.(b) Bleach (sodium hypochlorite, NaOCl, a strong oxidizing agent) neutralizes and inactivates mustard gas. Bleach is also effective on organic stains because it oxidizes coloredcompounds to colorless compounds. Propose products that might be formed by thereaction of mustard gas with bleach.
1. What type of reaction is occuring in step 3? (halogenation, hydrohalogenation, reduction, keto–enol tautomerism, dehydrohalogenation, acid-catalyzed hydration, base-catalyzed hydration) 2. Which reagent is necessary for step 3? (Br2, HBr, H2/Pt, NaNH2, H20/H2SO4/HgSO4)
When (CH3CH2)3CBr is added to CH3OH at room temperature, the major product is (CH3O)C(CH2CH3)3 and a minor product is CH3CH=C(CH2CH3)2. Propose a mechanism for the product that is formed by the substitution reaction. Use curved arrows to show the movement of electrons.
