Functional Groups of Organic Compounds A functional group is a specific arrangement of atoms in the HC derivative other than carbon and hydrogen. Literally‚ the functional group determines the functions of the particular HC derivative in chemical reactions. This means that the specific properties of the HC derivative are due to its functional group. Each functional group is attached to an alkyl radical (R). An alkyl radical is one H atom less than the given alkane. The alkyl radical (R) uses

Engineering)‚ a functional requirement defines a function of a system or its component. A function is described as a set of inputs‚ the behavior‚ and outputs (see also software). Functional requirements may be calculations‚ technical details‚ data manipulation and processing and other specific functionality that define what a system is supposed to accomplish. Behavioral requirements describing all the cases where the system uses the functional requirements are captured in use cases. Functional requirements

function. Such function may be defined at the level of an occupational sector‚ an enterprise‚ a group of enterprises or a whole sector of production or services. Functional analysis may be developed with different initial levels: an occupational sector (hotel); mainstream occupations at various sectors (occupational safety and health); or an occupation (PC repairman). It is thus evident the flexibility of functional analysis. Although it was designed as a wide-scale analysis tool‚ it may also be useful to

Yes‚ We Do Matter I’ve always heard that it only takes one person to make a difference in this world‚ and that one person is going to be me. I matter in this world because‚ I’m a loving wife‚ and wonderful mother to my two children. Although I’m not a wealthy person‚ I can describe myself as an ambitious‚ generous‚ vivacious and very eager to learn woman. I have a few goals in life‚ and one was to teach my children that just because they don’t have money‚ it doesn’t mean they don’t have wealth

organic chemistry Scope Organic chemistry is a vast subject so it is easier to split it into small sections for study. This is usually done by studying compounds which behave in a similar way because they have a particular atom‚ or group of atoms‚ (FUNCTIONAL GROUP) in their structure. Catenation The ability to form bonds between atoms of the same element. Carbon catenates to form chains and rings‚ with single‚ double and/or triple covalent bonds. Q.1 • Why does carbon form so many

five-membered thiozolidine ring. The carbon atom of the amide on the β-lactam ring can be bonded to any substituent‚ called the ’R-group’. Penicillins as well as cephalosporins are called beta-lactam antibiotics and are characterized by three fundamental structural requirements: the fused beta-lactam structure (shown in the blue and red rings‚ a free carboxyl acid group (shown in red bottom right Figure1.1)‚ and one or more substituted amino acid side chains (shown in black). The lactam structure

Functional Competency Inventory and Design by Jai Cortes I. Title of the Diagnostic Tool: Functional Competency Inventory and Design II. Overview of the Diagnostic Tool a. Definition In a nutshell‚ functional competency inventory and design‚ is a tool which aims to measure the competencies of functional groups of organizations‚ which are affected by their respective core objectives. In 1973‚ McClelland supported “testing for competence‚ rather than intelligence.” By definition‚ competencies

This spectrum was shown with different absorption bands corresponded with the functional groups of aspirin which was observed at frequencies > 1500 cm-1. These infrared frequencies were shown in Table 2. An infrared spectrum of an authentic aspirin was used to distinguish how authentic the infrared spectrum from the synthesis was shown
