JEE Mains · Chemistry · STD 12 -8.1. Aldehydes and ketones
The correct statement about the synthesis of erythritol \((C(CH_2OH)_4)\) used in the preparation of \(PETN\) is
- A The synthesis requires three aldol condensations and one Cannizzaro reaction
- B Alpha hydrogens of ethanol and methanol are involved in this reaction.
- C The synthesis requires two aldol condensations and two Cannizzaro reactions
- D The synthesis requires four aldol condensations between methanol and ethanol
Answer & Solution
Correct Answer
(A) The synthesis requires three aldol condensations and one Cannizzaro reaction
Step-by-step Solution
Detailed explanation
The pentaerythritol is typically produced a base - catalyed reaction of acetaldehyde with excess formaldehyde. the aldol condenstion of three moles of formaldehyde with one mole of acetaldehyde is followed by a crossed cannizzaro reaction between pentaerythritol product and…
