Organic Chemistry II Laboratory (ABCT357) Although studying fundamental theories of chemistry in the class is important to understand the concept of chemistry‚ carrying out experiments to corroborate the theories is also important. It is very important for students to get used to experiments in order to speed up their experiments. Expt.1. Acetylation of α-D-glucopyranose Add slowly 2.5 g (0.014 mol) of powdered D-glucose in small portions (roughly in 7-10 portions and 5 min for each addition)

ions Reagent/ Condition; Reaction | Explanation | Oxygen supply; Combustion | Limited supply of oxygen: CO formed.Even less Oxygen: C is deposited as soot. Excess Oxygen: Complete combustion (giving CO2 and H2O) | Al2 O3 and vaporisation of alkane at 500°C; Cracking of Alkanes | Al2 O3 is used as a catalyst. Heat provides energy for breakage of C-C bonds. | UV light; Initiation step of FRS of alkanes by halogens * Not required for electrophilic addition reaction btw Halogens and alkenes

Experiment H: Identification of an Unknown Organic Compound The objective of this lab was straightforward. We were given an unknown compound and we were to perform an IR spectroscopy and as well as NMR spectroscopy. With the IR spectroscopy‚ I was able to name the functional groups I have on my compound and further confirmed my assumptions by looking at the NMR spectroscopy after. The unknown number I was given was number 203. The molecular weight of the compound was 121. From the molecular weight

Geography 5 April 2013 The Green Revolution refers to the application of modern‚ western-type farming techniques to less economically developed countries. Organic farming is a type of agriculture that uses natural forms of growing crops. In this essay I will address the comparative similarities and differences between The Green Revolution and organic farming. The Green Revolution occurred between the 1940’s and 1970’s. It consisted of using genetically modified seeds‚ pesticides‚ hormone insertion into

Introduction We can grow healthful food without depending too much on toxic chemicals and chemical fertilizers with NATURALORGANIC AND BIOLOGICAL FARMING systems. The knowledge and simple but practical technology in this manuscript can save your crops and help you earn more from your garden and farm. Let’s return to the “Natural” ways. ABSTRACT A natural and effective mosquito repellent. It contains the natural oil‚ citronella‚ which is safe and effective; in fact‚ lemon grass citronella is considered

on the organic food market in Europe Introduction Since global consume in organic food products has increased during the last few years and their trend is increasing continuously‚ European countries are considered for one of massive portion of global demand.(p80) So‚ the purposes of the reported were firstly‚ compare markets demand for organic foods. Secondary‚ distinguish organic food consumers. Finally‚ describe marketing plan and the potential future development of the European organic market

Mechanistic Vs Organic Organization Structure What is Mechanistic Structure Mechanistic organizations have clear‚ well-defined‚ centralized‚ vertical hierarchies of command‚ authority‚ and control. Efficiency and predictability are emphasized through specialization‚ standardization‚ and formalization. This results in rigidly defined jobs‚ technologies‚ and processes. The term mechanistic suggests that organizational structures‚ processes‚ and roles are like a machine in which each part of the
