Classify the functional groups in the following steroid (choose all that apply).CHOOSE ALL THAT APPLY a. tertiary alcohol b. amide c. alkene d. secondary alcohol e. alkyne f. primary alcohol g. carboxylic acid h. aldehyde i. ester j. ketone

(ii) H2SO4 (aq) R'OH R +HO R CHO. R (i) (ii) (iv) (v) You are an organic chemist working with a team to produce a fruit scented ester using Fischer esterification. Upper management would 1ike your team to increasc the percent yield of this ester. Each team member suggests an idca: i. Decrease thc initial concentration of compound 1. as this will drive the production of more ester. ii. Increasc thc concentration of compound 3. as this will increase the rate of the forward reaction. iji, Increasc the concentration of compound 2 t5 be in excess of compound 1. iv. Add hygroscopic scrubbers to remove water from the reaction. Which of thesc statcments will provide the solution that management wants? (i) and (i) (ii) only ). (), and (iv). 20. m.and (i)
