I only need question 2 and 3 please !

Pre-Lab/ln-Lab Assignment: 1. Copy the following table into your lab notebook. For each of the common organic substances listed, draw the structure, fill in the boiling tempetature (in C ), the molar mass (in g mol) and the finctional groups present. 2. The retention times of cach mubitance ase listed in the graph above. a) Discus the retention times of the six rubstanses with regand to their molecular weights. Describe any pattem that emerges and propose an explanation. b) Discuss the retention limes of the sis subatanses with regard to their boiling points. Deicribe any pattem that emerges and propose an explanation. c) Diseuss the retention times of the uis rabitances with regard to their functional frougs. Describe: any pattem that emerges and propose an explanation. 3. The mass spectra of ethanol is listed below. Identify the labeled peakx. Draw structures for each of the indicated m z values.
