AS Chemistry | Live Class 23 | Chemical Bonding Part 5 | Past Paper Questions
Welcome to AS Chemistry Live Class 23! In this session, we complete Chemical Bonding (Part 5) with intensive past paper question practice, helping students refine their understanding, improve exam technique, and gain confidence for AS Level Chemistry examinations.
1️⃣ Quick Revision of Chemical Bonding Topics –
This section briefly revises key bonding concepts, including covalent bonding, VSEPR theory, molecular shape, bond polarity, and intermolecular forces. This revision ensures students recall essential ideas before attempting exam-style questions.
2️⃣ Past Paper Questions on Molecular Shape –
Students practise exam questions related to VSEPR theory, lone pairs, bond angles, and molecular geometry. Each question is explained step by step, focusing on how examiners expect answers to be structured.
3️⃣ Past Paper Questions on Intermolecular Forces –
This point covers real exam questions on hydrogen bonding, dipole–dipole interactions, and van der Waals forces. Students learn how to compare substances clearly and link intermolecular forces to boiling points and physical properties.
4️⃣ Explaining Trends and Comparisons –
Students are taught how to explain trends using correct chemical language, such as changes in molecular size, polarity, and strength of intermolecular forces. This skill is essential for high-mark explanation questions.
5️⃣ Common Exam Mistakes & How to Avoid Them –
Frequent errors such as confusing intermolecular forces with covalent bonds, missing key terms, or writing vague explanations are highlighted. Practical tips are provided to avoid losing easy marks.
6️⃣ Examiner Tips for Full Marks –
This final section shares examiner-style advice on time management, answer structure, diagram clarity, and use of key terminology to maximise marks in AS Chemistry exams.
