UNIT 1: Carboxylic Acids and Their Derivatives (13 Lectures)

1. Preparation of Carboxylic Acids

Oxidation Reactions:

Primary alcohols → Carboxylic acids (using KMnO₄, CrO₃, etc.)

Aldehydes → Carboxylic acids

Ketones (via haloform reaction in methyl ketones)

Ester Hydrolysis:

Acidic hydrolysis: RCOOR’ + H₂O → RCOOH + R’OH

Alkaline hydrolysis (saponification): RCOOR’ + OH⁻ → RCOO⁻ + R’OH

2. Important Reactions

Hell-Volhard-Zelinsky Reaction:

α-halogenation...

The basic dictum of financial planning is “Earlier the Better”. According to this principle, Project ‘B’ is preferable. The profit maximisation goal ignores the time value of money.(iii) It ignores the Quality of Benefits: If the predicted earnings are more assured, the quality is high because the range of fluctuation is small. Profit maximisation ignores the value of benefits and does not consider the risk connected with profits. The following table demonstrates this:(Quality of Benefits-

Describe the structure and bonding in sodium chloride. Sodium chloride is an ionic compound. It contains positive sodium ions (Na⁺) and negative chloride ions (Cl⁻). The ions are held together in a giant lattice by strong electrostatic forces. These forces act in all directions, giving it a high melting point.

Explain why potassium is more reactive than lithium Both are in Group 1 and have 1 electron in their outer shell. Potassium’s outer electron is further from the nucleus. So there is...

Required Practical 1: Making Soluble Salts Aim: Prepare a pure, dry sample of a soluble salt from an insoluble base (e.g., copper(II) sulfate from copper oxide). Method: Add excess copper oxide to warm sulfuric acid and stir. Filter to remove excess base. Evaporate water to crystallise the salt. Leave to cool and dry the crystals. Key Points to Remember: Ensure excess base is used to neutralise all acid. Avoid boiling; use gentle heating to prevent spitting. Filter carefully to remove all unreacted...

1. Research Design: Meaning, Classification, and Elements

Meaning and Purpose Research design is the overall blueprint or roadmap that guides the entire research process. It defines the procedures necessary to collect, analyze, and interpret data in a way that answers the research questions or tests hypotheses. In essence, it is the structure that provides coherence to the research process, ensuring that every element—from problem definition through data collection to final analysis—is aligned

1. Indicate the methods and principles of research in the theory of translation. Translation experiment.

Research Methods in Translation Theory:

Translation studies employ various research methods to explore translation processes, strategies, and outcomes. Key methods include:

Descriptive Studies: These analyze existing translations to identify patterns, norms, and strategies used by translators.

Comparative Analysis: This involves comparing source texts (ST) and target texts (TT) to examine how...
