Why is the melting point for vanillyl alcohol so much higher than that of vanillin?
Vanillyn alcohol has a much higher melting point than vanillin because vanillyn alcohol involves intermolecular hydrogen bonding interactions, while vanillin has weak interactions that lead up to a stable compound.

What is the catalyst in reduction of vanillin?
Consequently, what is the catalyst in reduction of vanillin? Sodium borohydride reduces the aldehyde group in vanillin to primary alcohol. To ensure the reaction to go to completion, an excess amount of sodium borohydride will be used in the reaction.
Which is the best method for the purification of liquids?
Purification of Liquids 1 Distillation. The underlying principle behind distillation is that the mixture of liquids can be separated by the difference in their boiling points. 2 Fractional Distillation. This method is employed when the difference between the boiling points of the liquids isn’t much. 3 Vacuum Distillation. …
How are impurities removed from an organic compound?
Purification means the removal of unwanted impurities present in an organic compound. The general methods of purification are: Some solids can directly pass to the vapour state without going through the liquid phase. The purification technique which exploits this property is called sublimation.
How is sodium borohydride used to dissolve vanillin?
Sodium borohydride reduces the aldehyde group in vanillin to primary alcohol. To ensure the reaction to go to completion, an excess amount of sodium borohydride will be used in the reaction. Furthermore, how do you reduce Vanillyl to vanillyl alcohol?
