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]
Question 2 0/2 pts In the reaction of a ketone with sodium borohydride with methanol, the Select ) is the nucleophile while the [Select] is the electrophile. Answer 1: You Answered You left this blank) Correct Answer hydride Answer 2: You Answered (You left this blank) Correct Answer carbonyl carbon Haier
1. Because NaBH4 is a mild reducing agent, it must be used with a protic solvent such as methanol to facilitate the reaction. This results in a side reaction between the borohydride and the methanol resulting in the production of hydrogen gas (the fizzing you observed during the addition of the reagent. Use curly-arrows to show the Bronsted acid-base reaction of one equivalent of BH4 - with methanol. 2. For the reason shown above, a fair excess of sodium borohydride...
Carbon monoxide gas reacts with hydrogen gas to form methanol via the following reaction: CO(g)+2H2(g)→CH3OH(g) A 1.70 L reaction vessel, initially at 305 K, contains carbon monoxide gas at a partial pressure of 232 mmHg and hydrogen gas at a partial pressure of 355 mmHg . Identify the limiting reactant and determine the theoretical yield of methanol in grams
