The purpose of this study was to identify the effect of using 3D-visualization on learning nucleophilic substitution reaction to improve students' critical thinking ability. This study used quasi experimental pretest and postest design. This study involved 68 students from two different universities in West Java. University A have 37 students and university B have 31 students involved at the study. The critical thinking ability test instrument consists of 9 multiple choice questions with reasons. The results show that learning using 3D-visualization on nucleophilic substitution reaction can improve students' critical thinking ability. Based on the N-gain result, students of the university A better than the university B, except on 'identifying/formulating criteria to assess posible answers' indicator of critical thinking ability. It should be increase students' critical thinking skills especially in the university B through further effort. © Published under licence by IOP Publishing Ltd.
