Tematy:: substituted aryl benzohydrazide
IR spectra
NMR spectra
hammett equation
substituent constants
correlation analysis
Opis:: A series of some aryl hydrazides have been synthesized. These hydrazides purities were analyzed by physical constants and spectral data. The assigned spectral group frequencies were correlated with Hammett substituent constants and Swain-Lupton parameters using single and multi-linear regression analysis. From the results of statistical analysis, the effect of substituents on the spectral group frequencies has been discussed.

Tematy:: Substituted Schiff’s bases
leaf-discs bio assay
Insect antifeedant activity
Opis:: Some substituted aryl Schiff’s bases[(E)-N-substitutedbenzylidene-4-methoxyanilines] have been prepared and their purities were checked by their physical constants and spectroscopic data reported earlier. The insect antifeedant activities of these Schiff’s bases have been studied by leafdiscs bio assay method using 4th instar larvae Achoea Janata L.

Tematy:: Oxo-propyl diazenyl benzoic acid chalcones
IR spectra
NMR spectra
Hammett equation
Regression analysis
Opis:: A series of titled compounds were prepared and analyzed their purities by literature method. The infrared and NMR spectral group frequencies of the compounds were assigned and correlated with Hammett substituent constants, F and R constants using single and multi linear regression analysis. From the results of statistical analysis, the effect of substituents on the above spectral frequencies was discussed.
