Chemistry subjects are difficult and abstract subjects, so many learners do not meet the Minimum Completeness Standard (KKM). The difficulty of students in understanding chemistry is marked by the inability of students to understand chemical concepts correctly. Hydrocarbons are an important part of chemical materials and require a high mastery of concepts. So that high-level thinking skills are needed, In order to overcome these problems, teaching materials that can guide students to find concepts are needed. This research aims to develop a guide-based query-based hydrocarbon module and reveal the effectiveness of the module. This module was developedmental using a 4-D model, which consists of 4 stages, namely (1) the define stage, (2) the design stage, (3) the develop stage, (4) the deseminated stage. But in this study, the desseminated stage was not carried out. The data collection instruments consist of questionnaire sheets and interview sheets. This module is validated by 5 experts in their fields. Use Aiken's V formula to analyze the validity test data, including content, structure, language and graphical components. The data analysis shows that the level of validity on the aspects of the content, construct
