The correct statement about the synthesis of erythritol used in the preparation of PETN is that it requires three aldol condensations and one Cannizzaro reaction.
Explanation:
Aldol condensation is a reaction that involves the formation of a carbon-carbon bond through the condensation of an aldehyde or ketone with an enolate ion or another carbonyl compound. The Cannizzaro reaction is a redox reaction that involves the disproportionation of an aldehyde into an alcohol and a carboxylic acid.
In the synthesis of erythritol, three aldol condensations and one Cannizzaro reaction are involved. Let's break down the steps involved in this synthesis:
1. First aldol condensation:
- Methanol (CH3OH) reacts with formaldehyde (CH2O) to form aldol product 1.
- The alpha hydrogen of formaldehyde is involved in this reaction.
2. Second aldol condensation:
- Ethanol (CH3CH2OH) reacts with aldol product 1 to form aldol product 2.
- The alpha hydrogen of ethanol is involved in this reaction.
3. Third aldol condensation:
- Aldol product 2 reacts with formaldehyde (CH2O) to form aldol product 3.
- The alpha hydrogen of formaldehyde is involved in this reaction.
4. Cannizzaro reaction:
- Aldol product 3 undergoes a Cannizzaro reaction to give erythritol (C(CH2OH)4) and formic acid (HCOOH).
- The Cannizzaro reaction involves the disproportionation of aldol product 3, with one molecule being reduced to erythritol (alcohol) and the other being oxidized to formic acid (carboxylic acid).
Therefore, the correct statement is that the synthesis of erythritol requires three aldol condensations and one Cannizzaro reaction. The alpha hydrogens of ethanol and methanol are involved in these reactions.
