Preparing for MDCAT 2025? You already know Chemistry plays a crucial role in your entry test success. With hundreds of concepts to cover, it’s important to focus on the most relevant and high-weightage topics. Let’s dive into the top 10 Chemistry topics that will help you score big.
1. Chemical Bonding
Questions from this topic are common in every MDCAT. Focus on:
- Types of bonding (ionic, covalent, metallic)
- Shapes of molecules (VSEPR theory)
- Bond polarity and hybridization
2. Thermochemistry
Thermochemistry is concept-heavy but scoring. Key areas:
- Enthalpy change
- Heat of formation, combustion
- Exothermic vs Endothermic reactions
3. Chemical Equilibrium
Often tested through MCQs involving Kc, Kp:
- Le Chatelier’s Principle
- Equilibrium constant calculations
- Effect of concentration, temperature, and pressure
4. Acids, Bases, and Salts
Don’t ignore the calculations here:
- pH & pOH formulas
- Conjugate acid-base pairs
- Buffer solutions
5. Reaction Kinetics
Expect numerical questions from this topic:
- Rate laws and order of reaction
- Effect of catalysts and temperature
- Graphical analysis of rate
6. Organic Chemistry Fundamentals
This is a vast but high-yield topic:
- Hydrocarbons (alkanes, alkenes, alkynes)
- Functional groups
- Isomerism and IUPAC nomenclature
7. Biochemistry
Many students skip this — don’t!
- Proteins, carbohydrates, lipids
- Enzyme action
- Vitamins and their functions
8. Periodic Table & Periodicity
Must-know chapter for MCQs:
- Trends (atomic radius, electronegativity)
- Group and period properties
- Transition elements
9. Electrochemistry
- Redox reactions
- Electrochemical cells
- Standard electrode potentials
10. Environmental Chemistry
Conceptual but easy to master:
- Greenhouse gases
- Water treatment
- Air pollution
