Expert Solution
Step 1
Identification of organic compound can be done by spectroscopic techniques.
The techniques are : IR, 1H-NMR and 13C-NMR.
Chemical shift value of a proton/C depends on the electronic environment. Greater is the electron deficiency, higher will be the chemical shift value.
Splitting of a proton is based on the (n+1) rule where n is the no of chemically non-equivalent protons.
