The slide explains the electrophilic addition of hydrogen halides, such as HCl, to alkenes like but-2-ene, which follows Markovnikov's rule to produce 2-chlorobutane as the main product. It includes an interactive animation of the reaction mechanism and highlights its industrial importance in synthesizing alkyl halides.

• Electrophilic addition to alkenes like but-2-ene.
• Follows Markovnikov's rule for regioselectivity.
• HCl adds to form 2-chlorobutane product.
• Interactive animation illustrates reaction mechanism.
• Key in synthesizing alkyl halides industrially.

The slide illustrates the halogenation of but-2-ene with bromine (Br₂), resulting in the formation of 2,3-dibromobutane through an anti addition mechanism. It highlights the key steps, including the creation of a bromonium ion intermediate and the subsequent nucleophilic attack by a bromide ion from the opposite side, leading to a stereospecific trans addition product.

The slide discusses the catalytic hydrogenation of but-2-ene using Pd/C and H₂, which saturates the double bond to produce stable butane, a key process in industry for converting alkenes into alkanes used in fuels and organic synthesis. It also covers the acid-catalyzed hydration of but-2-ene following Markovnikov's rule, adding H₂O with H₂SO₄ to form butan-2-ol, essential for producing alcohols in solvents, pharmaceuticals, and beverages with high selectivity.

Hidrogenación e Hidratación

The slide discusses the oxidation of but-2-ene using KMnO4, which cleaves the double bond to yield two molecules of acetic acid. It also covers the acidic character of terminal alkynes, such as but-1-yne, where the terminal hydrogen can be deprotonated by NaNH2 to form an acetylide ion.

Oxidación de Alquenos y Carácter Ácido de Alquinos

• Oxidación con KMnO4 de but-2-eno produce ácidos carboxílicos.
• Doble enlace se cliva en dos moléculas de ácido acético.
• Alquinos terminales exhiben carácter ácido por hidrógeno terminal.
• Desprotonación de but-1-ino con NaNH2 forma ion acetiluro.

This slide introduces Part B of the presentation, titled "Parte B: Aplicaciones de Reacciones," focusing on practical uses of chemical reactions. The subtitle highlights applications of hydrogenation, halogenation, and hydration in medicine, industry, and food sectors.

Parte B: Aplicaciones de Reacciones

Usos prácticos de hidrogenación, halogenación e hidratación en medicina, industria y alimentos.

In medicine and industry, hydrogenation is essential for synthesizing stable steroid drugs and producing durable polymers from unsaturated compounds for plastics and rubbers. In the food sector, it transforms vegetable oils into solid fats for margarines and baked goods, though it creates trans fats linked to cardiovascular risks that should be avoided in healthy diets.

Hidrogenación: Usos

Halogenation finds key applications in medicine through organic iodine-based disinfectants used for antisepsis. In industry, it enables PVC synthesis via ethylene chlorination, while in food preservation, regulated chlorinated compounds serve as conservants.

Halogenación: Aplicaciones

• En medicina: Desinfectantes con iodo orgánico para antisepsia.
• En industria: Síntesis de PVC mediante cloración de etileno.
• En alimentos: Conservantes clorados regulados para preservación.

The slide, titled "Hidratación: Ejemplos Prácticos," presents practical examples of hydration in various applications through an accompanying image. It highlights perfumes in cosmetic medicine, ethylene glycol as an industrial antifreeze, and syrups in food industry products.
