Interpretation:
Number of signals expected in each of the following compounds in
Concept introduction:
The signals in the spectrum of a compound are proportional to the number of carbons that are present in the different environment within the molecule. The carbon which is present in the electron-rich environment shows a signal at a lower frequency and vice-versa. Therefore, the carbons that are present nearest to the electron-withdrawing groups produce a high-frequency signal.
