Homework Help: Basic organic chem q's

  1. Apr 4, 2009 #1
    Hello. I have a couple of questions.

    Why are the boiling points of alkenes lower than alkanes?

    My thinking: something with van der waas forces?. Not sure.

    Why do haloalkanes have higher boiling points than alkanes?

    My thinking: dipole-dipole forces?

    What is an experiment that can be used to identify an alkane, an alkene and a carboxyllic acid from eachother?

    My thinking: Test 1) Bromine water test to identify alkane. Test 2) then to differentiate between carboxyllic acid and alkene, react them with a base, and you will be left with an alkene?

    What is a test that can be used to test yeast fermentation?

    My thinking: yeast in closed container with sugar. then test alcohol content at certain intervals?. I need some help here on how to design a better test.

    Thanks in Advance.
