In this study with high school students, a descriptive scanning model, one of the qualitative research methods, was used to determine the extent to which the achievements of the hybridization occurred. The study was conducted with 12th grade students studying in a public high school in Bursa in 2017-2018 academic year. According to the findings obtained from the research, it was determined that most of the high school students had difficulty in explaining the formation of single, double and triple bonds using atomic and hybrid orbital knowledge and expressing it verbally and schematically. It has also been found that students have problems in identifying the hybridization type which the central atom in the given organic compound undergoes. For this reason, it has been concluded that it is important to explain hybrids in detail at a high school level, taking advantage of teaching techniques and materials, paying attention to visuality during teaching and exploiting three-dimensional models.
