The concept of organocatalysis Acceleration of chemical processes through addition of substoichiometric quantity of organic compound refers to organocatalysis. In the last few years, interest in this field has increased because of selectivity and efficiency of many organocatalytic reactions, which have met standards of the required organic reactions. Observably, organocatalytic reactions are becoming popular in constructions of complex molecules. This recent development is because the process is less toxic compared to metallic catalysts. Predominant molecules used in the organocatalytic reaction are carbon, hydrogen, nitrogen, sulphur and phosphorous (McMurry, 2009). Organocatalysts usually display secondary characteristics, which would lead to enamine catalysis or iminium catalysis. The mechanism involved is covalent organocatalysis. High catalysts loading apply in covalent binding of substrates while non-covalent bonding requires low substrate loading. Knoevenagel Condensation applies regular achiral organocatalysts, which uses nitrogen as its basis. The current focus of organocatalysis is asymmetric organocatalysis, which involves the use of chiral catalysts. Scientific reactions indicate asymmetric catalysis occurs when organocatalyst is chiral as observed in aldol reactions (McMurry, 2009). Organocatalysts have the following advantages they are less sensitive to moisture or oxygen, readily available, less toxic, and inexpensive (Berkessel, 2006). These advantages make organocatalysts preferable in pharmaceutical processes. During the chemical reactions toxin produced usually influence usage of certain chemical process. Notably, organocatalysis has less impact to the environment. The condition for the reaction is relatively mild thus making organocatalysts preferable over metal catalysts. The following example illustrating Knoevenagel Condensation indicates that Piperdine forms iminium ion, which is reactive with carbonyl compound. Fig 1: Retrieved from http://www.organic-chemistry.org/topics/organocatalysis.shtm B. Definition of terms Catalyst is a chemical substance that increases the rate of a chemical reaction but does not change its chemical composition at the end of the chemical process. Organocatalyst are catalysts, which contain organic compounds. Enamine catalysts refers to a compound that forms when ketone or aldehyde react with secondary amine resulting into a loss of Water. Imine is a compound that contains carbon hydrogen double bond. Covalent bonding refers to a chemical bonding process where atoms share electrons. Covalent bonding occurs between non-metallic atoms. Chiral is a term used to describe a molecule that does not fit on its mirror image (Reetz & Joroch, 2008). Achiral refers to molecules that are identical or fit into their mirror image. Asymmetric organocatalysis refers to organic synthesis, which leads to introduction of desired element of chirality (Berkessel, 2006). This technology applies in pharmaceuticals since different enantiomers of molecule contain different biological components. Aldol reaction refers to a method that leads to formation of carbon-carbon bonds. Knoevenagel Condensation this refers to carbon acid compound condensation using aldehydes to produce unsaturated ? and ? compounds (Berkessel, 2006). ...Download file to see next pagesRead More

...? Practical Report on Children and Young People’s Self Identity Children and young people exhibit differences in the way they behave and how they relate with other people, which constitute their personality and individual character traits. This largely involves how children develop a sense of identity in the way they see themselves and how other people view them. This sense of identity develops and changes through a period of time along their childhood. Every person has a unique gradual development of a sense of autonomous and individuality which is relatively different from other people. This concerns the child’s social behavior and his own view about how people relate with him or her depending on the expectations of...

...? Practical: Examining 6 to 12 Year Old Children’s Understanding of Why Some Objects Float and Others Sink This study tried to explore how children of different ages explain why some objects float while others sink. Data was collected from two female participants between the ages of 6 - 12 years who studied in the same school via a video-recorded session with a researcher. Each child was shown a number of items and asked to predict whether it would float or sink and to provide explanations. They were also challenged on inconsistencies. It was found that children did indeed try to develop a consistent theory for why some objects float and others sink, and that maturity was associated with more complex explanations. The involvement... ...

The country has made a compulsion for bars and clubs to put and follow a sign that it does not allow students and are meant only for those aged above twenty - one. It has also reduced working hours in pubs and bars (Luty, 2005). Colour coding with name tag has been used to identify persons below 21. The hosts are responsible for not serving alcohol to those aged below twenty - one. Cash Bars are prohibited and also cover charges for attending teenagers. All receptions who serve alcohol with food are limited to one hour time limit only (University of North Carolina, n.d.).

... Fungicides are chemical substances that are widely used to compromise the growth of pathogenic fungi. It’s applied on the surfaces of the plant and can work locally or systematically. Fungicides also exhibit different degree of action; some can be used to control a wide range of fungi hence referred to as wide spectrum or can only be used to control specific species of fungi termed as narrow spectrum fungicide. Mode of action The fact that fungicides can control a wide range of fungi elicit the question of how this happens, some of the advanced reasons as to how the fungicides work include the following; there are...

...Attributes Of Fear in Achievement Research question: What damage can fear cause in one’s ability? A dispute can clearly be seen in the two texts on the impact of the word broken. According to Franklin, ‘broken’ can be used in two ways; first she talks about it being used positively, that is, a contestant was told by the judges that she looked good broken. This is a positive comment that used the word ‘broken’, as the judges praised the picture. It is also seen that the judges use ‘broken’ in a negative way, whereby, they say “You look like the broken Tin Man”. Franklin concludes, “sometimes looking broken is good; sometimes it’s not”. However, she dislikes the criticisms...

James must draw as much information from them as possible, filling gaps with his own expertise. Visual Visual tools can enhance and aid James in teaching, as then he can invite the students to participate in the lecture, which would keep them alert to the auditory environment as well. Kinesthetic James can adapt Kinesthetic learning strategy by asking students to use similes, metaphors and symbols in their daily conversations. He can initiate it by forming two teams, dividing up the class, and initiating a competition among them. This would...

...as a device that is passive in nature and is used for the purpose of storing up energy for use in its own electric field. Any item which can be charged electrically and store energy, can be assumed to be a capacitor. The authors reiterate that the capacitor comprises of two plates, which are usually separate from each other by the use of a dielectric. The two plates are good conductors of electricity and that is why they are separated by an insulator. A capacitor is used in the situation where huge amounts of charge are to be distributed within a short time. The book notes that a capacitor’s charge level depends on the amount of voltage that is applied to the capacitor....
