The goal of this experiment was to synthesize dibenzalacetone by aldol synthesis. The name ’Aldol synthesis’ was taken from the words ’aldehyde and alcohol’. This is because the product of this reaction contains both an aldehyde and alcohol. The carbon-carbon bond-forming reaction is referred to as aldol addition. An aldol condensation yields many species of products if the reactant is more than one. Therefore‚ the aldehyde has to react with itself to yield one product. Procedure: Followed according

Report Aldol Reaction Purpose: The purpose of this experiment is to be able to conduct an aldol condensation reaction using an unknown aldehyde and an unknown ketone. H NMR is used to identify the unknown aldehyde and ketone. Melting point is used to identify the aldol condensation reaction. Theory: Condensation reaction is also known as a dehydration reaction. In the mechanism of condensation reaction‚ a bond is formed between two molecules and creates water as a byproduct. Aldol condensation

I picked the second quote‚ “trans fats should not be banned. Consumers should make their own choices about what they eat. The government should educate the population about the risks of eating foods with Trans fats‚ but then let people make their own decisions.” The way I look at this situation is‚ we do a lot of bad things to our bodies. We eat fast food‚ sugars‚ drink alcohol and plenty more. Everything that we take into our body systems‚ has some type of effect on our bodies‚ whether it be causing

Ban Trans-Fat Although fats are considered to be a part of our health‚ there are certain types that should be ignored. One of which has drawn controversial issues is trans-fat. Trans-fat is mostly found in many food sources such as vegetable oil‚ crackers‚ cookies and margarine. It increases blood levels of low density lipoprotein that is considered to be bad cholesterol‚ and decreases level of good cholesterol‚ high density lipoprotein. Trans-fat is created when oils are partially hydrogenated

Institute a State-wide Ban of the Use of Trans Fat? Trans fats are a type of fat often used in preparation of fried foods in order to enhance the flavor and‚ in some cases‚ increase the shelf life of a product‚ but these inexpensive‚ artificially produced fats have been liked to heart disease because they increase levels of bad cholesterol in the body while lowering levels of good cholesterol and that is why I agree that we should ban the use of trans fats in New Jersey restaurants and food establishments

Trans Fats There is lots of controversy going on about should the trans fats be banned by the government or not. On one side are people who are for ban of trans fats‚ while their opponents think that they should not be prohibited. What are the trans fats? Are they really bad for our health‚ should they be replaced with another substance and why there are so many people against them? Producers have the power over us‚ as well as opportunity to put trans fats into food in small amounts‚ without

unconscious when the mind redirects a thought or word dangerous or unacceptable and substitutes it with a more affable thought or word. Condensation; where all the different elements‚ bits and pieces of thought and dreams combine into one to make sense. In this way they can stand for several different thoughts‚ feelings‚ wishes‚ ideas‚ etc. For Freud‚ condensation and displacement / substitution were used as a defense mechanism to contain aggressive and sexual impulses and hide the true unconscious
