Introductory Organic Chemistry

Introduction to Organic Chemistry

• Organic chemistry is integral to everyday life and various professional fields, including chemistry, bioscience, medicine, and environmental sciences.
• Essential for industries such as pharmaceuticals, molecular biology, biochemistry, biotechnology, polymer science, petrochemicals, textiles, adhesives, resins, and dyes.

Definition and Scope

• Focuses on carbon compounds, excluding some exceptions like CO2 and Na2CO3.
• Best defined as the chemistry of hydrocarbons and their derivatives.
• Hydrocarbons consist solely of carbon and hydrogen; derivatives include compounds derived from hydrocarbons.

Fundamental Concepts in Chemistry

• Chemistry is termed a "central science" that studies matter, its composition, structure, properties, and the changes it undergoes during reactions.

Common Elements in Organic Compounds

• Hydrogen (H), Carbon (C), Nitrogen (N), Oxygen (O), and Fluorine (F) are majorly involved in organic compounds.

Key Properties of Elements in Organic Chemistry

• Hydrogen: Atomic Number 1, exists as a gas (H2), electron configuration of 1s¹, has isotopes H, 2H, and 3H.
• Carbon: Atomic Number 6, solid state, with electron configuration 1s² 2s² 2p² or [He] 2s² 2p², isotopes include ¹²C, ¹³C, and ¹⁴C.
• Nitrogen: Atomic Number 7, gas (N2), electron configuration 1s² 2s² 2p³ or [He] 2s² 2p³, with isotopes like ¹⁴N.
• Oxygen: Atomic Number 8, gas (O2), electron configuration 1s² 2s² 2p⁴ or [He] 2s² 2p⁴, isotopes include ¹⁶O and ¹⁸O.
• Fluorine: Atomic Number 9, gas (F2), electron configuration 1s² 2s² 2p⁵ or [He] 2s² 2p⁵, with isotopes like ¹⁹F.

Summary of Periodic Table Elements in Organic Chemistry

• The elements listed mainly belong to groups 1, 2, and 14-18, displaying unique properties crucial for understanding organic reactions and structures.
