Concept explainers
Interpretation:
The range of chemical shifts in the given compound is to be determined.
Concept introduction:
Nuclear magnetic resonance (NMR) is one of the most capable analytical techniques used for determining the functional groups and how the atoms are structured and arranged in a molecule.
A compound containing protons or carbon-13 when placed under very strong magnetic field and treated with
Nuclear magnetic resonance spectroscopy is a graph showing characteristic energy absorption frequencies and intensities of a compound under magnetic field.
Chemical shifts are positions of signals along the x-axis in the nuclear magnetic spectroscopy. It gives an idea on how many different hydrogen atoms are present in a given H-NMR for a particular compound.
More electronegative atoms attached to the group, more the protons are deshielded; more will be the chemical shift value.
Answer to Problem 1PP
Solution:
Chemical shifts for ethyl acetate are at
Explanation of Solution
Structure of ethyl acetate
From the structure, we have three types of hydrogens and from table 9.1 chemical shifts result in the values as follows:
The chemical shifts are in the ranges of
