Halogenoalkanes What is the name of this halogenoalkane? How could you make it from butan-1-ol? Alcohols How could you make ethanol from ethene? How does ethanol react with sodium, in what ways is this a) similar to the reaction with water, b) different to the reaction with water? Aldehydes and ketones Draw the structures of a) propanal b) propanone How are these two functional groups different?

A100 kmol/h stream that is 97 mole% carbon tetrachloride (ccl4) and 3% carbon disulfide (cs2) is to be recovered from the bottom of a distillation column. the feed to the column is 16 mole% cs2 and 84% ccl4, and 2% of the ccl4 entering the column is contained in the overhead stream leaving the top of the column. calculate the mass and mole fractions of ccl4 in the overhead stream, and determine the molar flow rates of ccl4 and cs2 in the overhead and feed streams. 12. mw_ccla- 153.82; mw_cs2-76.14.
