(a)
To determine: The structure of cellulose acetate.
Interpretation: The structure of cellulose acetate is to be drawn.
Concept Introduction: Cellulose is the
(b)
To determine: The reason for cellulose acetate being soluble in organic solvents.
Interpretation: The reason for cellulose acetate is soluble in organic solvent even though cellulose is not is to be explained.
Concept Introduction: Solubility obeys the principle of ‘like dissolve like’ which means polar solutes dissolves in the polar solvent and non polar solute dissolves in non polar solvents.
(c)
To determine: The reason for the given observation.
Interpretation: The reason for the disintegration of acetate blouse into a pile of white stuff on the action of acetone is to be explained.
Concept Introduction: Solubility obeys the principle of ‘like dissolve like’ which means polar solutes dissolves in the polar solvent and non polar solute dissolves in non polar solvents.
(d)
To determine: The fact which comes true as a result of the given action.
Interpretation: The fact which results when students wear polyvinyl chloride shoes to the organic laboratory is to be stated.
Concept Introduction: Solubility obeys the principle of ‘like dissolve like’ which means polar solutes dissolves in the polar solvent and non polar solute dissolves in non polar solvents.

- a. The first three lines of this procedure describe the reaction used to make compound 5b. In the fourth line, hexane and sodium bicarbonate are added. What organic lab technique is being used here? b. What is the purpose of the Na2SO4? c. What equipment would you use to “concentrate [a solution] under reduced pressure”?arrow_forwardWhen N,N-dimethylaniline is treated with bromine both the ortho and para products are observed. However when treated with a mixture of nitric acid and sulfuric acid only the meta product is observed. Explain these results and support your answer with the appropriate drawings *Hint amines are bases* N HNO3 H2SO4 N NO2 N Br2 N Br + N 8-8-8 FeBr3 Brarrow_forwardDraw a mechanism that explains the formation of compound OMe SO3H 1.

- Consider the following two acid-base reactions: OH OHI Based on what you know about the compounds and their acidity, which direction would you expect both of these reactions to proceed? Show your reasoning. A pKa table has been provided in case you need it. Functional group Example pka CHA -50 Alkane -35 Amine : NH3 Alkyne RH 25 Water HO-H 169 16 10 Protonated amines NH 10 5 Carboxylic acids OH Hydrochloric acid HCI A chemist intends to run the following reaction on the three substrates shown below: H₂O R-CI product room temp. Cl Cl (1) (2) (3) They find one will react quickly, one slowly, and one will not react at all. Which is which, and why? HINT: What is the reaction they're trying to do? Does that mechanism tell you anything about why something would be favored?arrow_forwardNH3 decomposes through an equilibrium reaction between NH3, H2, and N2. Only one of the options is correct:(A). The mechanism of the NH3 decomposition reaction must necessarily involve the collision of two NH3 molecules to induce a rearrangement of the atoms in this molecule.(B). The molecular weight of the NH3 decomposition reaction is 2 since two NH3 molecules must collide.(C). The rate of the NH3 decomposition reaction must be greater than that of NH3 synthesis, since the former requires two molecules to collide and the latter, four.(D). The NH3 decomposition reaction cannot occur in a single step.arrow_forwardGiven the equilibrium A2 + B2 ⇌ 2 AB where k1 is the rate coefficient of the forward reaction and k-1 is the rate coefficient of the reverse reaction, with the forward reaction being first-order in A2 and B2, and the reverse reaction being second-order in AB. Equilibrium will be reached later if the relative values of the constants are:(A) k1 high and k-1 high(B) k1 high and k-1 low(C) k1 low and k-1 high(D) k1 low and k-1 lowarrow_forward
