The study aimed to investigate the properties of thermodynamics, acoustics, and electromagnetism in order to understand the interactions between molecules both within and between different compounds. The study also examined how molecular shape and structure, as well as temperature and the presence of chlorine atoms in alkanes and alkenes, influenced these properties. Measurements were taken for densities (ρ), speeds of sound (u), and refractive indices (nD) in various mixtures containing acetophenone with 1,2-dichloroethane, 1,1,1-trichloroethane, 1,1,2,2-tetrachloroethane, trichloroethene or tetrachloroethene at temperatures ranging from 298.15 K to 318.15 K. Additionally, excess molar volumes (VE m), isentropic compressibilities (Ks), excess isentropic compressibilities (휅SE), and excess refractive index (nE D), were calculated. The quantities were correlated with the Werblan relation. The VE m values exhibited negative for all mixtures except for acetophenone+ 1,2-dichloroethane which had positive values while the tetrachloroethene system showed both positive and negative values. The (휅SE), values were showed negative for all binary mixtures. Lastly, the(nE D) values for acetophenone with 1,2-dichloroethane were negative and with tetrachloroeth
