pls explain the reaction of the preperation og dibenzalacetone by mixed condensation
1. In the introduction the crossed-adol condensation reaction to
produce dibenzalacetone is discussed. This reaction require 1
equivalent of acetone for every 2 equivalents of benzaldehyde to
produce the desired product. What side product would you expect if
not enough acetone was used?
2. What reagents and in what equivalent would you use to synthesize
benzalacetophenone?
3. How would you synthesize 2-ethylhex-2-en-1-ol from
butanal?
4. Draw the resonance structure for the following enolate
ions:

Dibenzalacetone Synthesis PURPOSE: purpose of this lab exercise is to synthesize dibenzalacetone by means of an aldol condition. INTRODUCTION: Wow, is it wet in here or what? That's what happens when you condense, right? No, that is not right, you say! You can condense things without getting wet in organic chemistry. Think about aldol condensations, you tell me. Yes. yes..of course you are correct: organic condensations dont get you wet. They get you a new product. Silly me Aldol condensation...

The Aldol condensation: Synthesis of dibenzalacetone
I need help with question 4 and the second part of 5 please.
nzaldehyde via the aldol condensation. 2. What is the role of sodium hydroxide in this reaction? 3. Explain formation of the double bonds in dibenzalacetone. 4. Construct a model of dibenzalacetone to show structure and geometry. Are there other possible geometric isomers? 5. Research the most stable isomer based on melting point and geometric structure. cluas vield next week
Full mechanism of reaction needed: A double crossed aldol condensation reaction will be carried out. The reaction uses the simple starting materials, acetone and benzaldehyde, to form the 17-carbon product known as dibenzalacetone.
For an Aldo-condensation reaction. Explain why the condensation reaction occurred even though no “heat” was provided.
