EXPERIMENT 1: REACTIONS OF ENOLATE IONS WITH CARBONYL GROUPS Aims In this experiment we used two techniques for the reactions of enolate ions with carbonyl groups. One technique used was Doebner reaction and the other technique used was Claisen-Schmidt reaction. Therefore the aim of this experiment is to synthesize trans p-methoxycinnamic acid and to synthesize dibenzalacetone via an aldol condensation reaction between acetone and benzaldehyde. The products would be recrystallized using ethanol

Experiment 2: IDENTIFICATION OF UNKNOWNS BY TLC AND MP IN COMBINATION Introduction: Thin layer chromatography (TLC) is one of the most valuable techniques in organic chemistry. This is a best method of separating and identifying mixtures of two or more compounds. The separation is accomplished by the distribution of the mixture between two phases: one that is stationary and one that is moving or mobile. Chromatography works on the principle that different compounds will have different

FIRE RESISTANT BALLOON: Materials - 1 matchbox - 1 candle - 1 yellow colored balloon - 1 blue colored balloon - Half a cup of water Procedure: 1. For this experiment‚ the independent variable is whether the balloon is filled with water or not. The dependent variable is what happens to the balloon when it is placed above the lit candle. This is determined by observing the balloon. The constants (control variables) are how much the balloon is inflated and the amount

process of distillation. Distillation is the separation of volatile substances mixed with nonvolatile substances by boiling the mixture to alter the phase of the volatile substance. The researchers used the simple distillation set up to conduct the experiment. 25 ml of The Bar Vodka was used and 7 ml of distillate was collected before a temperature of 95 degrees Celsius was reached. Collected distillate was then subjected to a flammability test to confirm ethanol content. The percent ethanol was computed

Conformity is seen everywhere throughout life. People conform when they are trying to pick which restaurant to go to‚ or which movie to see. People conform all the time without even being conscious about doing it. Conformity affects a school-age child’s educational experiences. Although the negatives outweigh the positives there is some positives of conformity. In society normal is just seen as acceptable‚ people who conform do not run the risk of being excluded or bullied by their peers. Conformity

Asch carried out an experiment in 1951 to investigate the extent to which social pressure from a majority group could affect a person to conform. Asch used a lab experiment‚ where 50 male students from a college in the USA participated in a ‘vision test’. Using a line judgement test‚ one of the more naïve participants was put in a room with 7 confederates. The confederates had agreed in advance what their responses would be involving the line task. The real participant didn’t know this‚ and was led

Conformity to majority influence Types of Conformity Kelman (1958) proposed three types of conformity: Compliance – going along with others to gain their approval or to avoid their disapproval Internalisation – going along with others because you have accepted their point of view because it is consistent with your own Identification – going along with other because you have accepted their point of views because of a desire to be like them Compliance When exposed to the views or actions of

Discuss research findings into conformity ( 12 marks) Conformity is a form of social influence where a person adopts the behaviors‚ attitudes and values of other members of a reference group. Conformity is a normal process in which everybody adopts to fit in and be liked and many psychologists have completed research into these fields. Deutsh and Gerard claimed that there were two types of conformity. Normative influence is motivated by a desire to fit in with a group and be liked‚ and informational

In chapter 7‚ Solomon begins exploring and discussing the prospect of death. At one point or another‚ our lives will come to an end‚ and when that day comes‚ we tend to look more closely at our Adam II qualities more than ever. To start the chapter off‚ Solomon begins with a brief history about the denial of death. His basic premise comes from a writer by the name of Ernest Becker. In Becker’s final book‚ he pointed out that we--as Americans--had purposefully buried ourselves within our day-to-day
