(a) Interpretation: On the basis of 13 C NMR, the compounds α , α − dimethylsuccinic acid and adipic acid are to be differentiated. Concept introduction: Carboxylic acid is a class of organic compound that contains a − COOH group attached with a hydrocarbon chain. The name of these compounds ends with a suffix − o i c a c i d or − i c a c i d . The 13 C NMR spectroscopy is similar kind of spectroscopy the only difference is that it is used to detect the presence of 13 C nucleus. The natural abundance of 13 C nucleus is only 1.1 % while 12 C nucleus is not detectable by NMR spectroscopy. The difference between its resonance frequency and that of the reference standard is known as the chemical shift of a nucleus. The ( n + 1 ) rule is applicable on the protons attached to the same carbon whose splitting pattern is to be determined.
