1. draw a mechanism for the conversion of methoxybenzyl alcohol to methoxybenzaldehyde. 2.The ethyl acetate layer was extracted with 0.2M NaOH to remove traces of methoxybenzoic acid that result from additional oxidation of the aldehyde to the carboxylic acid. Explain how crystals of methoxybenzoic acid could be isolated from the NaOH solution. 3. Explain how TLC could be used to monitor the reduction of methoxybenzaldehyde to methoxybenzyl alcohol using NaBH4 as a reducing agent.

A mixture is 11 mol% ethanol, 79 mol% ethyl acetate (C4H8O2) and 10 mol% acetic acid (C2H4O2). (a) Calculate the mass fraction of ethanol in this three-component mixture. (b) What is the average molecular weight of the three-component mixture? (c) What would be the mass (kg) of the three-component mixture such that the mixture contains 24 kmol of ethyl acetate? (d) A stream of the three-component mixture enters a mixing drum at 78 kg/min. For a basis of 78 kg/min,...

A mixture of 4-methylphenol and 4-methylcyclohexanol was run on a TLC plate using 3:1 hexane:ethyl acetate as the eluent. Only one spot was seen using a UV lamp. Does this mean that both spots have the same Rf or is there another explanation? How might you solve this problem?
