Draw the structure of the product that forms when the carbonyl compound shown is treated with K₂ Cг2 О7. If no reaction occurs, draw the structure of the organic starting material (reactant). CH3(CH2), (CO)CH (CH3)2 Click and drag to start drawing a structure. : ☐

Identify the Lewis acid in the following reaction: A. BF3 B. F C. BF4 D. None of these is an acid. B OD O A O C

For the following reaction at equilibrium NH3 + H20 + NH4+1 + Он-1 NH3 is the It is not a hydroxide and so is a base. H20 is the It is both a very acid and a very base. NH4*1 is the It is not on the list of strong acids and so is a acid. OH-1 is the . It is a base because it contains hydroxide. а. acid b. base c. conjugate acid d. conjugate base e. strong f. moderately strong or weak g. weak

3. Show the calculation of (1) the expected grams of alum (KAI(SO4)2 12 H2O) formed from the reaction of 1.4 grams of aluminum metal and then show the calculation of (2) the % yield if the actual yield of alum is 21.31 grams. Overall reaction is shown below: 2 Al + 2 KOH + 10 H2O + 4 H2SO4 →2 KAI(SO4)2 12 H2O + 3 H2(g)T
