a)
Butanol + butaneamine --> no, amines rearly form azeotropes
b)
butyl acetate + butanol --> no azeotrope
c)
expect azeotrope formation
expect due to hexanol + hexane
d)
cycohexane + benzene -->azeotrope formation at 45.0% by weight of Cyclohexane

Prelab 9: Selective Media Read pages 227-230 and 241-256 in your lab manual, watch the video, and answer the following questions in your own words before coming to lab. Chapter 6 in your textbook may also be helpful. You may also want to review the video on inoculation techniques. (I will hand out a written procedure for the KOH test in lab.) NOTE: for all these procedures over the next few weeks, you will be testing only your assigned organism...
MSISTRY 203-204 Grganic Chemistry Lab Manual 3 4 EXPERIMENT #9 The Preparation of t Butyl Chloride A tertiary carbonium ion is more rapidly formed than a secondary or primary carbonium ion. Once formed, a tertiary carbonium ion is stabilized by charge dispersal to a greater extent than a secondary or primary carbonium ion. It therefore has a longer life expectancy. Primary carbonium ions, protons, may exist in solution only in solvated form have any free existence, they dehydration reaction and...
