Organic Chemistry: Carboxylic Acids, Amines, and Heterocycles
Unit 1: Carboxylic Acids and Their Derivatives
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
Important Reactions of Carboxylic Acids
Hell-Volhard-Zelinsky Reaction
- α-halogenation of carboxylic acids using Br2 + PBr3
- Mechanism:
The Call of the Wild Plot Summary: Buck’s Journey
Buck’s Early Life and Abduction
Buck, a powerful dog, lives a comfortable life in the Santa Clara Valley with his owner, Judge Miller. One day, Manuel, the Judge’s gardener’s assistant, steals Buck and sells him to pay a gambling debt. Buck is then shipped to the “Man in the Red Sweater” to be broken. Subsequently, Buck is shipped to Alaska and sold to a pair of French-Canadians named François and Perrault (for $300), who were impressed with his physique.

French Revolution’s Aftermath: Terror, Directory, and European Restoration
The Reign of Terror (1793-1794)
During this period, innocent people were put to death, and many others were beaten. Victims were often forced to comply and then left to resist for their lives. This era of terror began in 1793 and concluded in 1794.
Revolutionary Societal Changes
The revolutionary spirit ushered in a new era. This included:
- A new calendar
- The replacement of state festivals and other religious symbols with those of a revolutionary character
- Significant changes in fashion
- The adoption of
Spanish Industrial Evolution: 1855-1975 Analysis
Historical Development of Spanish Industry (1855-1975)
Early Industrialization (Late 19th Century)
The start of Spanish industrialization occurred late compared to other Western European countries. The causes were:
- Poor endowment in raw materials and some basic energy products.
- Low availability of entrepreneurial capital.
- Technological backwardness.
- Limited demand for industrial products.
- Preference for external markets/trade.
- Inadequate industrial policies.
Industrial Growth (Early 20th Century)
In the first

Marx’s View of Man and Alienation
Alienation, in Marx’s anthropology, is a historical situation resulting from a specific socioeconomic organization. This organization related to work constitutes human essence.
Characteristics of Man
- Man is a natural being with natural needs for subsistence. Work is the means to satisfy these needs.
- Man is not the only being that separates itself from nature through work; through work, man seeks to transform nature to serve his purposes.
- The consideration of work as
Spanish Restoration: Cánovas’s System and Cuban Conflict
Cánovas del Castillo’s Liberalism and Objectives
Antonio Cánovas del Castillo aimed to articulate a new model of liberalism, addressing endemic issues of the past: the partisan and exclusionary nature of moderate military interventionism in politics and the proliferation of civil strife. His two primary objectives were:
- To develop a constitution that would establish a bipartisan political system.
- To pacify the country by ending the war in Cuba and the Carlist conflict.
Foundations of the New Political

Key Concepts
Intonation: The melody of speech; the musical pattern of sounds.
Pitch: Variation in the voice’s frequency.
Stress: A combination of loudness, pitch, and duration applied to a syllable or word.
Tone: Differences in the pitch of the voice used to convey meaning or attitude.
High, mid, and low tones are produced by variations in vocal cord vibration.
English is not a tone language; it is an intonational one. Meaning is often conveyed not just by *what* you say, but by *how* you say it.
