Question
1.) Show the types of solvation interactions that might be expected when ammonium chloride is dissolved in ethanol. Consider solvation of both the cation and the anion.
2.) What substitution and elimination products (if any) might be obtained when each of the following alkyl halides is treated with sodium methoxide in methanol?
2-bromobutane, methyl iodide, trans-1-bromo-3-methylcyclohexane, (bromomethyl)cyclopentane
3.) what rate law would be expected for the reaction of cyanide ion with ethyl bromide by the SN2 reaction?
Explanation / Answer
1. The solvation interaction when the ammonium chloride dissolves in ethanol. The positive end of the ethanol surrounded by Cl- and the negative end surrounded by NH4+.
2.
a) The major product is due to eliminaton is 1-butene. The bromine carbon bond break due to deprotonation by sodium methoxide.
b) The product is ether CH3-O-CH3.
C) The product is methylcyclohexene.
d) The product is methylcyclopentene
3. The rate law would be Second order. As bromide ion is a good leaving group and cyanide ion act as the nucleophile.
