HO HW2. A student ran the Grignard reaction below. CH, MgBr diethyl ether 2-pentanone 2-methyl-2-pentanol Upon completing the reaction above (assume all workups), the student performs a crude NMR and FT-IR of the material prior to any purification. The spectra obtained are shown below: transmittance Use the spectra and the table found in the paper by Hugo E. Gottlich, Vadim Kotly, and Abraham Nudelman J. Org.
