For Odd Role Number Group Q1. How does a flowchart help a programmer in a program development? Ans. Flowcharts provide the visual representation of a concept and make it clear. A flow chart serves as a blueprint of the program. Flowcharts helps a programmer organize his/her thoughts in a logical order and their presentation. Program development without graphics may be less effective. In big projects it gets difficult to keep things together. Flowcharts provide flexibility‚ so that you can make

PI and ID Flowchart and Narrative The following information provides two flow charts and then a comparison of the information. These charts are performance improvement flow and the ADDIE model. Image 1 - Performance Improvement flow Image 2 – ADDIE model After reviewing both flows you can see that there are strong similarities. Both models require that analysis be completed first‚ this is important as the gap‚ need‚ or desire outcome must be determined. Using past data can show areas

Tie-Dye Grignard Synthesis Abstract: 4-Bromo-N‚N-dimethylaniline underwent a Grignard reaction with diethyl carbonate to produce a type of the tie-dye chemical triarylmethane. This specific triarylmethane produces a vivid crystal violet color when dyed. The experiment was first heated under reflux to produce the necessary Grignard reagent as a grey liquid. It was then reacted with diethyl carbonate and hydrochloric acid to produce crystal violet. The resulting chemical was very absorbent to

Megan Wierzbowski Organic II Laboratory Wed. 11-1:50 Title: Grignard Reaction with a Ketone: Triphenylmethanol Part 1 Objective: The goal of this experiment is to learn to make Grignard reagents. The reactions of the Grignard reagents with ketones form tertiary alcohols. These reagents are highly air- and moisture-sensitive materials. We will observe the formation of the Grignard reagents‚ which magnesium metal is transformed into organometallic salts. Experimental Procedure:

Grignard Synthesis of Triphenylmethanol Aim The aim of this experiment was to prepared Grignard reagent (phenylmagnesium bromide) from bromobenzene and magnesium‚ to use the reagent prepared to synthesise a tertiary alcohol (triphenylmethanol) by reacting reagent and ester (methyl benzoate)‚ and the product formed is analyse by infrared spectroscopy (IR)‚ melting point‚ thin layer chromatography (TLC)‚ gas chromatography mass spectrum (GCMS) and finally Nuclear Magnetic Resonance spectroscopy.

4.1 Recall the evanstonian‚ an upscale independent hotel that caters to both bussines and leisure travelers‚ introduced in chapter 3 in exercise 3.10. when a guest calls room service at the evanstonian‚ the room-service manager takes down the order. She then submits an order ticket to the kitchen to begin preparing the food. She also gives an order to the sommelier (i.e.‚ the wine waiter) to fetch wine from the cellar and to prepare any other alcoholic beverages. Eighty percent of room-service orders

FLOWCHART A flowchart is a type of diagram that represents an algorithm or process‚ showing the steps as boxes of various kinds‚ and their order by connecting them with arrows. This diagrammatic representation illustrates a solution to a given problem. Process operations are represented in these boxes‚ and arrows; rather‚ they are implied by the sequencing of operations. Flowcharts are used in analyzing‚ designing‚ documenting or managing a process or program in various fields.[1] Overview[edit]

Grignard Synthesis of Triphenylmethanol from Benzophenone Purpose: The purpose of this experiment was to synthesize the tertiary alcohol triphenylmethanol from a Grignard reagent‚ phenyl magnesium bromide. The Grignard reagent was synthesized from bromobenzene and magnesium and then reacted with benzophenone to produce triphenylmethanol. It was important that water be excluded from the reaction‚ in order to prevent the formation of benzene. The reaction of phenyl magnesium bromide and benzophenone

The Grignard Synthesis of Triphenylmethanol Organic Chemistry Lab II March 19‚ 2012 Abstract The purpose of this experiment was to synthesize the Grignard reagent‚ phenyl magnesium bromide‚ and then use the manufactured Grignard reagent to synthesize the alcohol‚ triphenylmethanol‚ by reacting with benzophenone and protonation by H3O+. The triphenylmethanol was purified by recrystallization. The melting point‚ Infrared Spectroscopy‚ 13C NMR‚ and 1H NMR were used to characterize and confirm

Bowles is the “Clinical Practice Improvement Consultant‚” who charts scores of processes. Her inputs are very important for efficient room processes and admission processes. As Diane’s assistant I would first acquaint myself with the flow of Diana’s flowchart. I would take a few days to study the various inputs and the process flows. Once this is done then I could suggest improvements if any. I feel that there is only place where there is a scope for improvement. This would also help in getting the rooms
