Answer #1

Chemical shift is a great tool to predict the nature of the carbon atom or group present in the compound. As proton NMR shows different chemical shifts for various protons in a compound similarly, C-NMR shows different chemical shifts value for chemically non-equivalent carbons Chemical shift range for C-NMR is higher than that of proton NMR and the range is from 0 -250 ppm Consider the standard chemical shift values for various carbon atom depending on the chemical environment as shown below: Chemical environment of C atom C-C C-O C-C (alkene C-C (aromatic riin Chemical shift 0-50 50-100 115-140 125-150 150-200 Consider the structure of the given of the compound and write the chemical shift values as shown below:
