1. Explain why the main reaction between acetophenone and anisaldehyde is the mixed aldol reaction rather than (a) self-condensation of acetophenone or (b) Cannizzaro reaction of anisaldehyde. 2. No more than 2 mL of water should be used to dissolve the 2 or 3 pellets of NaOH. Why is not a larger volume of water used? 3. Anisalacetophenone dibromide is much more soluble in CHCl3 than in CCl4. Suggest a reason for this difference. 4. Crystals of pure erythro-anisalacetophenone dibromide are white, whereas crystals of pure anisalacetophenone are light yellow. Suggest a reason for this difference in color. 5. Could trans-anisalacetophenone be isomerized to the cis isomer by irradiating it with UV light? Why or why not?
