Describe, in three steps, how you would synthesise phenylethylamine (C6H5CH2CH2NH2) from methylbenzene, giving reagents and conditions for each step. For each step, state the type of reaction that occurs.

Methylbenzene (C6H5CH3) can be reacted with chlorine in the presence of UV light. The type of reaction is free radical substitution, and this produces phenylchloromethane ...

Part 2: from the empirical formula, calculate the molecular formula if the molecular weight of the substance is 180 g/mol

Molcular weight of CH2O = 30 g/mol
180/30 = 6
Molecular formula = C6H12O6

Part 1: Calculate the empirical formula for a substance with the following composition: H 6.71%; C 40.00%; O 53.29%

C = 12 g/molO = 16 g/molH = 1 g/mol
Ratio of C = 40/12 = 3.33Ratio of O = 53.29/16 = 3.33Ratio of H = 6.71/ 1 = 6.71Divide largest value by smallest value = 6.71/3.33 = 2Empirical formula = CH2O
