The study of energy conditions has many significant applications in generalrelativistic and cosmological contexts. This paper explores the energyconditions in the framework of the most general scalar-tensor theory with fieldequations involving second-order derivatives. For this purpose, we use flat FRWuniverse model with perfect fluid matter contents. By taking power law ansatzfor scalar field, we discuss the strong, weak, null and dominant energyconditions in terms of deceleration, jerk and snap parameters. Some particularcases of this theory like k-essence model and modified gravity theories etc.are analyzed with the help of the derived energy conditions and the possibleconstraints on the free parameters of the presented models are determined.
