Potassium tert-butoxide is used as the base in an elimination reaction of 2-bromo-2- methylbutane. Explain qualitatively how the results of the experiment would differ when potassium tert-butoxide is used as the base instead of potassium hydroxide. A correct answer will identify how the result(s) would differ, and explain mechanistically why the result would differ.
What weight of malononitrile would be recovered by extraction with (a) three 100-mL portions of ether; (b) one 300-mL portion of ether.
