How many pi bonds are in a benzene ring
WebCurrently, we reported the synthesis of six novel salicylaldehyde-based thiosemicarbazones (BHCT1–HBCT6) via condensation of salicylaldehyde with respective thiosemicarbazide. Through various spectroscopic methods, UV–visible and NMR, the chemical structures of BHCT1–HBCT6 compounds were determined. Along with synthesis, a computational … WebBoth structures have pi-bonds.
