**ABSTRACT**

About nine titled compounds were synthesized by greener method and the purities of these methanones have been examined using their analytical and spectral data reported in literature. The infrared and NMR spectral data of these methanones were assigned and correlated with Hammett substituent constants, F and R parameters using single and multi-linear regression analysis. From the results of statistical analyses, the effects of substituents in terms of spectral quantitative structure activity on the spectral frequencies were studied.
