Reduction of 9-fluorenone: objective of this lab was to reduce 9-fluorenone (a ketone), to 9-fluorenol (an alcohol) using sodium borohydride as the reducing agent. Experimental data: 9-fluorenone: MW 180.20 g/mol mass used 0.6 grams methanol: MW 32.04 g/mol volume used: 6ml density: 0.792 NaBH4: MW 37.83 g/mol mass used 0.05 grams 9-fluorenol: MW 182.22 g/mol Balanced equation for the reaction is: 4C13H8O NaBH4 4CH3OH --> 4C13H10O NaB(OCH3)4 Calculate the potential yield (in grams) of 9-fluorenol for 9-fluorenone, methanol and NaBH4. From these potential yields identify the limiting reagent and theoretical yield.

The reactions shown here can be combined to make the overall reaction c(s) + h2o(g) ⇌ co(g) + h2(g) by reversing some and/or dividing all the coefficients by a number. a. c(s) + o2(g) → co2(g) k=1.363×10^69 b. 2 h2(g) + o2(g) → 2 h2o(g) k=1.389×10^80 c. 2co(g) + o2 (g) → 2 co2(g) k=1.477×10^90
