Question

1) Write the chemical equation, with the transition state, for the reaction between 2-bromo-2-methylbutane and potassium hydroxide in 1-propanol that gives the major product. Use condensed structural formulas, and show the 3-d structure of the transition state.

2) Write the chemical equation, with the transition state, for the reaction between 2-bromo-2-methylbutane and potassium tert-butoxide in tert-butyl alcohol that gives the major product. Use condensed structural formulas, and show the 3-d structure of the transition state.

Explanation / Answer

1. reaction between 2-bromomethyl butane and potassium hydroxide yields the hydroxy product by the reaction due to the polar solvent 1-propanol.

2. the reaction between 2-bromo methyl butane and potassium tert butoxide in t-butanol will yield the eliminated product due to the strong base and a not so protic solvent.

in both the reactions the lone pairs take part of the reaction and the ions generated.
