Web21 jun. 2016 · The three C−H bonds on each methyl group contribute a total of 6 more σ bonds. So, we have a total of 18 σ bonds. Inside the benzene ring, you have delocalized π electrons over six atoms. The major resonance structure has three π bonds; one for each double bond. So the result is 18 σ and 3 π bonds. Answer link Web11 apr. 2024 · The peak at 284.6 eV has been assigned to C–H bonds, while the peak at 286.1 eV has been attributed to C=O bonds. The signal at approximately 288 eV could be related to O–C=O [ 70 , 71 ]. In the [email protected] sample, a superposition of peaks from turmeric powder and Fe 3 O 4 was observed; in particular, the π − π * shake-up from …
