Intermolecular Forces - Questions

The Intermolecular Forces Concept Builder is comprised of 39 questions. The questions are divided into 13 different Question Groups and spread across three different activities. Questions in the same group are rather similar to one another. The Concept Builder is coded to select at random a question from each group until a student is successful with that group of questions.

There are three activities in the Concept Builder. Those three activities are differentiated as follows:

• Paragraph Completion: Question Groups 1-3 ... Complete a paragraph by selecting words and phrases from a bank. Each paragraph targets a different intermolecular force type - London dispersion forces, dipole-dipole interactions, and hydrogen bonding.
• Force Identification: Question Groups 4-9 ... Given a Lewis electron dot structure for a substance, identify if there are polar bonds present, determine if the molecule is polar or non-polar, and identify the types of intermolecular forces in the substance.
• Match That Color: Question Groups 10-13 ... Given the formula of three strategically-chosen substances, rank the substances in order of the strength of their intermolecular forces.

The questions from each group are shown below. Teachers are encouraged to view the questions in order to judge which difficulty levels are most appropriate for their classes. We recommend providing students two or more options. 

The Physics Classroom grants teachers and other users the right to print these questions for private use. Users are also granted the right to copy the text and modify it for their own use. However, this document should not be uploaded to other servers for distribution to and/or display by others. The Physics Classroom website should remain the only website or server from which the document is distributed or displayed. We also provide a PDF that teachers can use under the same conditions. We have included a link to the PDF near the bottom of this page.
