please answer all parts!!
4) Lexi was performing a reduction reaction (scheme below) using sodium borohydride on methyl acetoacetate. After completing the lab, Lexi realized she furgot to label the starting material IR and the product IR. Explain how you would determine the corresponding spectra. IR:2929-2849 \( \mathrm{cm}^{-1}, 1746 \mathrm{~cm}^{-1} \), and \( 178 \mathrm{~cm}^{-1} \) IR \( 2: 3438 \mathrm{~cm}^{-1}, 2974-2935 \mathrm{~cm}^{-1}, 1739 \mathrm{~cm}^{-1} \), and \( 1119 \mathrm{~cm}^{-1} \) a. Which IR corresponds to the starting material (methyl acctoacetate)? b. Which IR corresponds to the product? 1. Draw the structure of the product. d. Label any important peaks.
Q-a ; IR spectrum generally useful for identification of functional groups in unknown compound on basis of IR stretching frequency. On comparison of stretching/ bending frequencies one can identify functional groups in unknown compound. In Given comp
