1. Are there any deshielding effects seen in your NMR? What is causing this effect? 2. How many protons would be in a compound with this integration, 1: 1.5: 1: 1.5? 3. How many signals would you expect to see on an 'H NMR of aniline?, Why? 4. Can you determine the number of carbons using a 'H NMR? Why or why not?
