Concept explainers
(a.1)
Interpretation:
The least and most shielded proton or set of protons in the given compounds has to be determined.
Concept introduction:
Depending upon the electron density around the proton the chemical shift values of the proton varies relative to the reference signal.
The more the shielded proton less will be its chemical shift value and the corresponding signal will be produced at the right-hand side or lower frequency region.
The more the deshielded or less shielded proton more will be its chemical shift value and the corresponding signal will be produced at the left-hand side or higher frequency region.
Proton or set of proton attached near to the more electronegative or electron withdrawing atoms such as F, O, N is more deshielded or less shielded and vice versa.

Take the flasks off the hotplate once you have a clear solution and let them stand on the bench top for 5 mins and then allow them to cool as described below. Sample A-Let the first sample cool slowly to room temperature by letting it stand on your lab bench, with occasional stirring to promote crystallization. Sample B-Cool the second sample 1n a tap-water bath to 10-15 °C Sample C-Cool the third sample in an ice-bath to 0-2 °C Results: weight after recrystalization and melting point temp.
