2-Methylpropane And 2 Bromobutane Lab Report

Satisfactory Essays

When we added the 1% silver nitrate to the alkyl halides in the first part of the experiment the first two test tubes, containing 2-bromo-2-methylpropane and 2-bromobutane, became cloudy almost immediately. The 2-bromo-2-methylpropane and 2-bromobutanes’ cloud was light green in color. The 1-bromobutane precipitated, though more slowly than the first two tubes, and its cloud was white. We also noticed that the 1-chlorobutane never seemed to become cloudy or precipitate. This is likely because chloride is a worse leaving group than bromide is (due to the chloride anion being a smaller ion, it can’t “handle” the negative charge as well as the larger bromide anion, so it doesn’t want to leave the carbon it’s sharing the electron with in 1-chlorobutane).
