Answer : it is SN2 reaction (substitution nucleophilic bimolecular reaction) .
A solution of methanol is prepared by dissolving 34.1 mL of methanol in sufficient water to give a total volume of 103.4 mL. What is the percent-by-volume concentration of methanol?
A mixture contains acetone, methanol, 1-propanol, and water. The boiling points of the components are as follows: acetone (CH3COCH3), 50.5∘C methanol (CH3OH), 66∘C 1-propanol (CH3CH2CH2OH), 97∘C water H2O, 100∘C Which pair of the components would you expect to be the hardest to separate by distillation? Select the correct answer below: a. acetone and methanol b. acetone and 1-propanol c. acetone and water d. methanol and 1-propanol e. methanol and water f. 1-propanol and water
The Boiling Point Diagram of Methanol-Water (Figure 5.6) shows Mole Fraction of Water versus Temperature, °C. Using the following atomic weights and the density of methanol of 0.792 g/ml, a 41.5 % v/v methanol in water solution (41.5 ml methanol and 58.5 ml water) is what mole fraction of water? Round to 2 decimal points with no units. Remember that the density of water is defined in the metric system as 1. (C = 12, H = 1, N =...

In a coulometric Karl Fischer water analysis, 50.00 mL of methanol (no residual water) that contained 2.930 g of a water-containing sample required 5398 C to generate enough iodine to react with all of the water in the sample. Find the percent by mass of water in the sample.
Calculate the enthalpy of methanol (CH3OH) in kJ/mol from data below Mass of water : 10.00 g Temp. increase in water : 9.90 C Mass of methanol burned : 0.50 g
Sodium borohydride reductions are typically run in polar protic solvents such as methanol or water. Vanillin is only sparingly soluble in water or methanol, thus for this reaction vanillin was dissolved in 1.0 M NaOH (aq). Explain with the use of a reaction mechanism why vanillin is more soluble in 1.0 M NaOH than water. [2.0 Marks]
