🔥 CSCA Chemistry Mock Examination | Intermolecular Forces MCQ Explained

Intermolecular forces play a crucial role in determining physical properties such as boiling point, melting point, and solubility. These concepts are frequently tested in CSCA Chemistry examinations.

In this video, we solve an important CSCA Chemistry MCQ:
👉 Which intermolecular force is the strongest?

📌 Options Given:
A) Van der Waals forces
B) Dipole-dipole interactions
C) Hydrogen bonding
D) London dispersion forces

📌 Concept Behind the Question:
Intermolecular forces are attractions between molecules. Different types of intermolecular forces have different strengths.

📌 Explanation of Forces:
• London dispersion forces → Weakest, present in all molecules
• Van der Waals forces → General weak interactions
• Dipole-dipole interactions → Moderate strength between polar molecules
• *Hydrogen bonding → Strongest intermolecular force*

Hydrogen bonding occurs when hydrogen is bonded to highly electronegative atoms such as **N, O, or F**, resulting in strong attraction between molecules.

Examples of hydrogen bonding:
• Water (H₂O)
• Ammonia (NH₃)
• Hydrogen fluoride (HF)

📌 Correct Answer:
✅ *C) Hydrogen bonding*

📌 Why Hydrogen Bonding Is Strongest:
• High polarity of bonds
• Strong electrostatic attraction
• Significant effect on boiling point and structure

📌 Why this MCQ is important for CSCA?
✔️ Frequently asked theory-based question
✔️ Builds clarity on intermolecular forces
✔️ Helps compare different force strengths
✔️ High confidence, easy scoring MCQ

📌 Who should watch this video?
• CSCA Chemistry students
• Class 9–12 learners
• Students revising intermolecular forces
• Competitive exam aspirants
