Q41E
Question
Treatment of 1-phenyl-2-propenone with a strong base such as LDA does not yield an anion, even though it contains a hydrogen on the carbon atom next to the carbonyl group. Explain.
Step-by-Step Solution
Verified Answer
LDA does not yield an anion due to steric hindrance.
1Step 1: Given compound
The given compound is 1-Phenyl-2-propenone.
1-Phenyl-2-propenone
2Step 2: LDA does not yield an anion
LDA is a highly steric hindrance base. So, it will not deprotonate the highly crowded side proton of the compound.
Steric hinderance
Thus, LDA does not yield an anion with the compound.
