Concept explainers
Interpretation:
The structures of given forms of Y are to be determined with the help of the given data.
Concept introduction:
The infrared spectroscopy is generally used in the identification of structures as the
Infrared spectroscopy is a simple, instrumental technique, which helps to determine the presence of various functional groups.
It depends on the interactions of atoms or molecules with the
The molecules which have dipole moment are IR active and the molecules which do not have dipole moment are IR inactive.
The region for functional group lies from
Degree of unsaturation of compound or index of hydrogen deficiency can be calculated using expression as:
Here, C is the number of carbon atoms, N is the number of nitrogen atoms, X is the number of halogen and H is number of hydrogen atoms.
