The paper analyzes fifteen organic chemistry textbooks commonly used in Brazilian universities to examine intermolecular forces’ coverage in them. The findings revealed that the intermolecular forces are spread over a few pages (less than 1%) in a fragmented way, and over several chapters that do not provide enough information to help create a clear image in the student’s mind. Thirteen textbooks contained end-of-chapter problems related to intermolecular forces. However, less than 1.3% of the total (212) are associated with intermolecular forces. This deficient approach to intermolecular forces in Organic textbooks can lead to teachers’ lack of interest in teaching the subject, leading to students failing to learn this important organic chemistry topic.

The educational game Interactions 500 was extensively used remotely during the COVID-19 Pandemic as an activity at the Federal University of Ceará (Brazil) to help students review intermolecular forces. In the postpandemic years, the game was also used face-to-face in the classroom. However, Apple Store and Google Play Store removed it from their list of apps in April of the current year, claiming that "the app was not compliant with one or more of their Developer Program Policies". This happens due to frequent updates to app stores' security policies, requiring constant maintenance of applications, which is not always possible or feasible due to time or financial limitations. Therefore, any reader of the Journal of Chemical Education can no longer access and play the game published in 2020.Faced with this scenario, the authors decided to develop a 100% online version of the game, which does not require any app to work and allows students to play the game remotely or face-to-face using mobile devices or, now, computers. The online version is presented in this article along with a student evaluation of the game.
