Aldol Condensation Discussion: 1. Aldol condensation reactions take place in basic conditions‚ where a deprotonated enol becomes an enolate and proceeds to attack the aldehyde. Since the solution is basic‚ it is able to deprotonate the alpha carbons of the product‚ which forces the hydroxide groups to leave. The product is then considered to be dehydrated and unsaturated. In terms of our reaction‚ cyclopentatone is deprotonated to form an enolate‚ which then attacks the two molecules of p-tolualdehyde

Year: 2007 Source: Journal of Autism and Development Disorders This article was based on research done on children ages three to ten years around the temperament and reactions of children with Autism. It discusses the differences between those with Autism‚ and those without autism‚ specifically how they react‚ perceive‚ and overcome certain developmental musts in childhood. These results are taken from the Children’s Behavior Questionnaire‚ which present the sixteen dimensions of child perceptions

also to discuss the difference between grand jury and preliminary hearing. For the start of a criminal case it begins with the filing of a complaint‚ mostly someone reporting a crime or annoyance. Then an investigation is launched and if a crime was committed and a suspect with enough evidence against them they are arrested and that then goes into the courts for the setting of the bond and arraignment trail. The arraignment trail is set up as the trail where a plea is given. Depending on where

“Failure is the first step towards success” is one of the most heard quotes and is again and again told to us in every step of life‚ but how often do we realize its importance or live by its mantra? Honestly‚ we don’t! We just expect the fruit to come to us without working over its plant. Getting up requires falling. If a nine month old gave up trying to walk after his first fall‚ he would never be able to walk again‚ simply because he gave up. We can relate this to anything we do or anything we

Experiment 11: Synthesis of Dibenzalacetone by the Aldol condensation Introduction: The Aldol condensation reaction‚ under basic conditions‚ involves the nucleophilic addition of an enolate ion to another carbonyl group. The resulting product‚ a beta-hydroxy ketone or aldehyde‚ is called an aldol because it contains both and aldehyde group and the hydroxy group of alcohol. Condensations‚ including aldol condensation‚ combine two or more molecules‚ typically with a loss of a smaller molecule (including

Be brave to take the first step I have an unforgettable experience which is very special for me last year. My cousins and I went to Macau——a combination of east and west cultural city. We have long heard of the famous challenge project there from TV. It said Macau has a great challenge project integrating recreation‚ challenge‚ adventure and stimulation‚ which is 233 meters high from the Macau tower called bungee jumping. We went directly to the Macau tower as soon as we arrived at Macau
