The peak in
Concept introduction:
NMR is an analytical method that is utilized to identify the structure of a compound. It determines the framework of carbon-hydrogen bonds present in the compound.
Number of signals in the
The protons that are present in the different chemical environment are known as non-equivalent protons while the protons that are present in same chemical environment are known as equivalent protons.
Answer to Problem 1Q
Eugenol has 12 different hydrogen atoms. The three hydrogen atom present on the aromatic ring show peak around
Explanation of Solution
The structure of eugenol is as follows:
Eugenol has 12 different hydrogen atoms. The integration of peaks from right to left is 3:2:2:3:2.
There are two peaks for the three hydrogens around
There are two peaks for four hydrogen atoms around
There are two peaks for six around
