Outline a separation scheme for isolating pure isopentyl
acetate from thereaction mixture.
Interpret the principal absorption bands in the infrared
spectrum of isopentylacetate or, if you did not determine the
infrared spectrum of your ester, do thisfor the spec-trum of
isopentyl acetate shown in the previous figure. (Technique25 may be
of some help.)
