Question 9 1 pts Please choose every correct statement for the chemical shift, integration and spin-spin coupling The proton on the carbon having clectronegative oxygen is observed in the downfield compared to other proton on sp3 carbon. Intormation from the integration in 1H NMR is about the number of proton in the signal A singlet of proton sanal means that the proton has no deshielding ettch Olehin protons on so2 carbon are observed in the chemical shifts between 5-7 pum, The shape of signal in the 1H NMR is about the number of proton in next carbon The proton on the carbon having electronegative oxygen is observed in the downfield compared to other proton on sp3 carton Information from the integration in 1H NMR is about the number of proton in the signal Aset of proton signal means that the proton has no deshilding effect Olen protons on sp2 carbon are observed in the chemical shifts between 5-7 ppm. The shape of signal in the 1H NMR is about the number of proton in next carbon
