4.11.4 ELEMENTAL ANALYSIS
Elemental analysis of the synthesized compounds was carried out on
Vario EL Carlo Erba 1108 which showed calculated and found percentage
values of Carbon, Hydrogen and Nitrogen in support of the structure of
synthesized compounds. The spectral and elemental analysis data are given
for individual compounds.
