the reaction between a carboxylic acid and an alcohol (Figure 1). Figure 1. The General Reaction Equation of Ester Formation From A Carboxylic Acid & An Alcohol. Carboxylic acids contain the functional group –COOH whereas in ester’s the hydrogen is replaced with an R denoting any alkyl or aryl group; -RCOOR’. Esters with low-molecular weights are commonly used as components in the flavor’s and odors of many fruits & fragrances’ as well as to enhance foods & beverages. A food technologist may

SUBJECT: Organization Behavior Case-1- A WINDOW ON LIFE For Gilbert La Crosse‚ there is nothing quite as beautiful as a handcrafted wood-framed window. La Crosse’s passion for windows goes back to his youth in Eau Claire‚ Wisconsin‚ where he learned from an elderly carpenter how to make residential windows. He learned about the characteristics of good wood‚ the best tools to use‚ and how to choose the best glass from local suppliers. La Crosse apprenticed with the carpenter in his small workshop

(–C(O)–OH) as a functional group are called carboxylic acids. The –C (O)-OH group which itself is made up of a carbonyl group (>C=O) and a hydroxyl group (-OH) is called a carboxyl group (carb from carbonyl and oxyl from hydroxyl group). Carboxylic acid may be an aliphatic or an aromatic depending upon whether –C–OH is attached to an alkyl group ( or a hydrogen atom) or an aryl group. Their general formulas are; ALIPHATIC CARBOXYLIC ACID: R–C (O)–OH where R=H or an alkyl group. Example: AROMATIC

Amines and Amides Amine - an ammonia molecule (NH3) in which one or more H atoms are substituted by an alkyl or aromatic group. Amide - an organic compound with a carbonyl functional group (C=O) bonded to a nitrogen atom. Amines are the smaller and simpler products of the decomposition of larger and more complex organic compounds like proteins. They often have foul odours‚ as do many nitrogen compounds‚ such as the smell of rotting fish and decomposing animal tissue and are produced by

Systemic functional linguistics is the study of the relationship between language and its functions in social setting. In systemic functional linguistics‚ three strata make up the linguistic system: meaning (semantics)‚ sound (phonology) and wording or lexicogrammar (syntax‚ morphology and lexis). Systemic functional linguistics treats grammar as a meaning-making resource and insists on the interrelation of form and meaning. According to Halliday‚ language has developed in response to three kinds
