❓ Frequently Asked Questions

1. What is the difference between organic and inorganic chemistry?
Organic chemistry studies carbon-containing compounds, while inorganic chemistry focuses on all other elements and their compounds.
2. How do catalysts work in chemical reactions?
Catalysts provide an alternative reaction pathway with lower activation energy, allowing reactions to proceed faster without being consumed in the process.
3. What is the role of temperature in chemical reactions?
Higher temperatures increase molecular motion and collision frequency, typically increasing reaction rates according to the Arrhenius equation.
4. How do intermolecular forces affect molecular properties?
Intermolecular forces determine physical properties like boiling point, melting point, and solubility, with stronger forces leading to higher melting and boiling points.
5. What is the difference between exothermic and endothermic reactions?
Exothermic reactions release energy (negative ΔH), while endothermic reactions absorb energy (positive ΔH) from their surroundings.
6. How do pH and pOH relate to acid-base chemistry?
pH = -log[H⁺] and pOH = -log[OH⁻], with pH + pOH = 14 at 25°C. Lower pH values indicate more acidic solutions.
7. What is the significance of the periodic table in chemistry?
The periodic table organizes elements by atomic number and reveals periodic trends in properties, helping predict chemical behavior and bonding patterns.
8. How do oxidation and reduction reactions work?
Oxidation involves loss of electrons (increase in oxidation number), while reduction involves gain of electrons (decrease in oxidation number).
9. What is the role of entropy in chemical reactions?
Entropy measures disorder in a system. Reactions tend to proceed toward higher entropy (more disorder) when other factors are equal.
10. How do we determine the structure of molecules?
Various techniques including X-ray crystallography, NMR spectroscopy, and mass spectrometry are used to determine molecular structures and properties.
